Step-by-Step Instructions

Cooking grains in a saucepan on a stove
Start with a warm, fiber-rich grain base—rice, quinoa, or your favorite whole grain.
  1. Cook the grains.
    Rinse the brown rice or quinoa under cold water. In a medium saucepan, combine the grains with the water or broth and a pinch of salt. Bring to a boil, then reduce the heat to low, cover, and simmer until tender (about 20–25 minutes for brown rice, 15 minutes for quinoa). Turn off the heat and let it sit, covered, for 5 minutes, then fluff with a fork.
  2. Warm the beans with aromatics.
    While the grains cook, heat 1 tablespoon olive oil in a small pan over medium heat. Add the minced garlic and cook just until fragrant, 30–45 seconds. Stir in the cooked mixed beans, a pinch of salt, and pepper. Warm through for 2–3 minutes, then set aside.
  3. Prep the veggies and herbs.
    Thinly slice the red onion, shred the red cabbage, julienne or grate the carrot, dice the cucumber, slice the avocado, and roughly chop the herbs. Rinse and dry the leafy greens. Set everything in small piles or bowls so assembly is easy.
  4. Mix the kefir-herb dressing.
    In a small bowl or jar, whisk together kefir, olive oil, lemon juice or vinegar, Dijon mustard, honey or maple syrup (if using), chopped herbs, grated garlic, and salt. Taste and adjust with more lemon, salt, or herbs as you like. The dressing should be tangy, lightly creamy, and pourable.
  5. Lightly marinate the cabbage and onion (optional but recommended).
    To soften their bite and add extra flavor, toss the shredded cabbage and sliced onion with a tablespoon of the dressing and a pinch of salt in a small bowl. Let sit for 5–10 minutes while you assemble the rest.
  6. Assemble the bowls.
    Divide the warm grains between 4 bowls. Spoon the warm garlicky beans over one section of each bowl. Arrange piles of greens, cabbage-onion mixture, carrot, cucumber, avocado, and berries around the bowl so you see lots of color. Add generous spoonfuls of kimchi or sauerkraut to each bowl.
  7. Add fermented dairy and crunchy toppings.
    Dollop or drizzle plain yogurt around the bowl. Sprinkle with pumpkin seeds, sunflower seeds or hemp hearts, and a crack of black pepper. If you enjoy a little heat, finish with chili flakes.
  8. Dress and serve.
    Drizzle each bowl with the kefir-herb dressing just before serving. Taste and add a final pinch of salt, a squeeze of lemon, or a splash of olive oil if you like. Enjoy warm grains against cool toppings, creamy dressing, bright acidity, and that satisfying kimchi crunch.

Gut Health 2.0 Tips, Variations & Substitutions

Make It Vegan or Dairy-Free

  • Swap kefir and yogurt for unsweetened, live-culture coconut or soy yogurt.
  • Thin the yogurt with a tablespoon or two of water or oat milk to reach a dressing-like consistency.
  • Check that your kimchi is made without fish sauce if you’re fully plant-based.

Boost the Polyphenols

  • Use a peppery extra-virgin olive oil as your main fat.
  • Add a spoonful of cocoa nibs or a dusting of unsweetened cocoa to the dressing for a subtle chocolate note.
  • Top with more herbs (mint, basil, cilantro) and a sprinkle of turmeric and black pepper.

Low-FODMAP Adaptations (for Sensitive Guts)

If you’re following a low-FODMAP protocol with a clinician:

  • Reduce or omit garlic and onion; use garlic-infused olive oil instead.
  • Choose low-FODMAP beans in small portions (e.g., canned lentils well rinsed) or swap beans for grilled tofu or tempeh if tolerated.
  • Limit cabbage and adjust kimchi portions to what feels comfortable.

Change Up the Grains & Proteins

  • Try barley, farro, or sorghum for extra chew and beta-glucan fiber (if you’re not gluten-free).
  • Use tempeh, grilled salmon, or soft-boiled eggs for additional protein.
  • Fold a spoonful of white miso paste into the warm beans after cooking (off the heat) for extra umami and live cultures.

Storage, Meal Prep & Reheating

This rainbow grain bowl is ideal for meal prep, especially if you keep the fermented foods and dressing separate until serving.

How to Store

  • Cooked grains & beans: Store together in an airtight container in the fridge for up to 4 days.
  • Chopped veggies & herbs: Keep in a separate container, lined with a paper towel, for 3–4 days.
  • Dressing: Refrigerate in a jar with a lid for up to 4 days. Shake before using.
  • Kimchi / sauerkraut / yogurt: Store in their original containers; add to bowls just before eating.

Reheating Guidelines

  • Reheat only the grains and beans (microwave or stovetop) with a splash of water to keep them moist.
  • Keep kimchi, sauerkraut, and kefir dressing cold to preserve their live cultures and bright flavors.
Let the bowl cool slightly before adding ferments—think warm, not steaming—so your hardworking microbes stay alive and well.

Serving Suggestions & Complementary Dishes

This gut-friendly grain bowl is a complete meal, but you can easily turn it into a full “microbiome menu” by pairing it with:

  • A small glass of unsweetened kombucha or sparkling water with a splash of kefir for extra live cultures.
  • A side of toasted sourdough with olive oil and fresh tomatoes for more fermented grains and polyphenols.
  • A simple berry and dark chocolate square dessert for a gentle, polyphenol-rich sweet finish.
  • Green or herbal tea after the meal to extend the polyphenol party for your gut microbes.
