Another one from the MIL. I usually make a huge pan of this at least once a week. DH loves it (of course he does, it's his mom's recipe). Again not a lot of measurements here, can't mess it up.
Cut zucchini in coins. Heat saute pan over med-hi heat and put in some olive oil. Saute zucchini and several cloves chopped garlic until zukes are nicely browned. Add salt and pepper and lots of thyme (fresh if possible). Add a small amt of water (about 1/4 cup) and place lid on pan. Allow to steam to desired tenderness (DH loves them firmer, I like them nice and mushy). If desired sprinkle grated cheese over just before they are done. Good with any kind of strong flavored cheese, our favorite is parmesan.
