This meal plan focuses on accessible, fiber-rich, plant-based foods to promote a healthy gut microbiome. Ingredients are selected for their availability in most supermarkets. Unfortunately, due to work, I don’t have the time or facilities to prepare a meal, so I’m opting for a shake meal instead.

My own Ratatouille recipe
Here’s a simple and gut-friendly recipe to nourish your microbes while delighting your taste buds:
Ingredients
- 6 fresh tomatoes
- 1 can of chopped tomatoes
- Olive oil
- 6 onions
- 5 garlic cloves (germ removed, minced)
- 5 courgettes
- 2 aubergines
- 1 pepper (any color)
- Concentrated garlic or garlic paste (1 teaspoon, optional)
- Herbs (e.g., thyme, rosemary, or herbes de Provence, to taste)
- Salt and pepper (to taste)
Step 1
Using your preferred method, remove the skin from the tomatoes (I microwave them for around 10 minutes after making small cuts; the skin comes off easily).
Step 2
Cut all the vegetables into large cubes, approximately 2 cm by 2 cm.
Step 3
Heat olive oil in a large pot and sauté the onions and garlic (remove the germ from the garlic beforehand).
Step 4
Add the aubergines and cook for 10 minutes.
Step 5
Add the courgettes and pepper, then cook for another 5 minutes.
Step 6
Finish by adding the tomatoes (I add a can of canned chopped tomatoes) and cook for 30 minutes, then uncover and simmer for at least 1 hour, stirring occasionally.
You can add concentrated tomatoes, concentrated garlic and herbs if you want.
Step 7
Optionally, add a glass of dry white wine at the beginning of the covered cooking phase to enhance flavor.
Step 8
Season with salt and pepper to taste.
Enjoy your meal—and happy microbes
