Can be made ahead of time in large batches, but it's veg only so you gotta boil some chicken thighs or something in a pot next to it or cook up eggs on the side. this is a low FODMAP version.
Ratatouille:
3 to 4 tbsp olive oil
1 med eggplant (1 lb), chopped
salt and black pepper to taste
2 small zucchini (12 oz), chopped
1 large red bell pepper (8 oz), chopped
6 oz thin green beans (haricots verts)
2 1/2 cups unsalted diced tomatoes (from can, jar, etc)
3/4 tsp dried herbs (any combo of thyme, tarragon, rosemary, etc)
Red chile flakes or minced fresh red chile (optional)
1/3 cup chopped olives, such as kalamata
4 oz feta cheese, crumbled
Chopped fresh basil
In a large, wide sauté pan, heat about 1 1/2 tbsp of oil on medium high. Add eggplant, season with salt and black pepper, and cook, stirring freqently, until lightly browned (eggplant will not be soft and cooked through at this point), 7 to 10 minutes. Transfer to a large bowl. If a lot of brown bits are sticking to the pan, add about 1/4 cup water (or red wine). When it starts to simmer, scrape the bottom of the pan with a spatula to deglaze.
Heat about 1 1/2 tbsp of oil in the pan, still on medium high heat, and add the zucchini and bell pepper. Season with salt and black pepper and cook until lightly browned, 7 to 10 minutes. Add to bowl with eggplant. Deglaze pan again if you like. Add 1 to 2 tsp of oil. Add green beans and cook, stirring frequently, until lightly browned, about 3 minutes.
Add tomatoes to pan with green beans and bring to a simmer. Stir in eggplant, zucchini, bell peppers, dried herbs and chile flakes if using. Cover and simmer on medium to medium-low heat until vegetables are very tender and sauce has thickened, 25 to 30 minutes, stirring occasionally. If pan gets too dry before veggies are done add water as needed. Stir in olives. Season to taste with salt and black pepper.
Serve over polenta, pasta or quinoa. Sprinkle with feta and fresh basil.
