Yes.
Seconding ratatouille, for both the eggplant and the zucchini. Here’s one version, there must be hundreds:
Olive oil
One large or two smaller good strong cooking onions
Garlic, to taste (I use several cloves)
Sweet peppers, gold and/or red ripe, two or three
One standard or two or three Asian (or baby standard) eggplant
Two to six tomatoes, depending on size
Basil, to taste; about a handful of fresh leaves
At least some of the following, but these are optional:
Summer squash (yellow, zucchini, cousa, and/or pattypan)
Snap beans (any type or color)
Green and/or purple sweet peppers
Tomatillos
Some hot pepper if you like
Fennel
Any other vegetable you think might be good
Take a large heavy frying pan and add enough olive oil to cover the bottom. Peel and cut up onions and garlic (cut to bitesize or smaller as you like) and sauté briefly on medium heat. Wash other produce. Remove seeds from peppers. Slice peppers and eggplant and add to pan. (It’s not necessary to peel eggplant if the skins are tender.) Keep on medium heat, stirring occasionally, and adding a little more oil if necessary, while you cut up and add summer squash, tomatillos, and / or beans in approximately that order. Cut tomatoes into quarters (or smaller, if they’re really big ones) and add them to pan; put a lid on and simmer on moderate heat until all vegetables are just tender. Add basil leaves (whole or chopped) and simmer another minute or two. Serve with rice, potatoes, fish or meat, or just with good bread.
Any leftovers? Try cold the next day with a little good vinegar added.
This also freezes well.
And here’s an idea for the winter squash:
Squash Soup
2 medium onions
2 to 3 cloves of garlic
a tablespoon or two of olive oil
3 small to medium pieces of ginger or candied ginger
2 medium sweet potatoes
1 cup apple cider (sweet cider; though I suppose you could try the alcoholic version)
4 to 5 cups of water
Winter squash: About 3 lb of any winter squash, raw or leftover cooked
Wash sweet potatoes and remove any bad portions of skin
Peel winter squash, and cut up if raw (size of pieces doesn’t matter)
Sauté onion and garlic in olive oil briefly
Cut up and add the ginger (size of pieces doesn’t matter)
Cut up and add sweet potatoes (size of pieces doesn’t matter)
Add apple cider and water
Add winter squash (cooked or raw)
Bring to a boil and then simmer till all vegetables are soft
Put through a blender or food mill, if you want it really smooth;
or mash pieces with a potato masher if you don’t mind some chunks
Return to pot and reheat to serve
