Here's a favorite old recipe of mine that incorporates a ton of different-colored veggies into one fabulous dish. Super low calorie. It's basically a ratatouille.
1 eggplant, diced in 1" squares
1 onion, diced
3 stalks celery, chopped
1 orange bell pepper, diced (green works fine, too)
4-5 medium tomatoes, diced
8-10 oz. mushrooms, sliced
3-4 cloves of garlic, diced or pressed (to taste)
chopped fresh basil to taste (I like lots, at least a quarter cup)
salt and pepper to taste
1 1/2 tsp olive oil
Heat oil gently in skillet. Add eggplant, mushrooms, onion, celery and garlic; saute briefly or until onion is soft. Add tomatoes, basil, salt and pepper. Simmer gently till tomatoes are cooked down and remaining vegetables are tender.
You can also do this on the grill by simply dividing all ingredients between 4 foil packets, dousing lightly with olive oil and cook for about half an hour at medium heat.
Top with a sprinkle of Parmesan cheese if desired.
In addition to being a fantastic side dish, I like to use this as an omelet filling for breakfast. Great way to get in those vegetables first thing in the morning! Also nice over whole grain pasta.
And I didn't used to like eggplant, either.
Hope this helps!
