I'm one of those who makes it up as I go along, so I have a hard time putting recipes to paper. But here's an easy one for zucchini. It has made converts of many zucchini-haters I know. It only works with smaller zucchini - sliced rounds should be no larger than about 3 inches diameter. If your zucchini is bigger than that, shred it for zucchini cake instead (I have a recipe for that somewhere, too!)
Slice zucchini into rounds of about 1/2 inch thick
slice mozzarella cheese, enough to cover each zucchini round completely
combine chopped garlic and butter in a frying pan. Lay zucchini rounds evenly to fill pan. Add salt and pepper to taste. Fry at medium heat. When slightly browned, turn each round over and cook until zucchini is lightly browned on both sides (don't overcook).
when zucchini is almost done, put mozzarella slices on top, turn off heat, and cover the pan. As soon as the cheese is melted, serve.
A variation is to add a slice of tomato under the cheese, or to mix cheddar and mozza cheeses.
