1 lb. zucchini, cut in half lengthwise and split into quarters
1/2 onion, sliced
1 green pepper, sliced in 1/2 inch widths
1 red pepper, sliced in 1/2 inch widths
1 tomato, cut in sections
1/2 lb. mushrooms, cleaned and quartered
1/4 to 1/2 lb. cheese, grated (Parmesan or cheddar)
1 c. Italian dressing

Marinate all the vegetables except tomato for several hours or overnight. Toss in the tomatoes and mushrooms; drain and spread out in large pan or cookie sheet. Turn on broiler and place pan about 2 inches from broiler. Watch closely and toss vegetables often. When all are cooked to the crisp-tender stage, sprinkle cheese over all and melt. Serve immediately.
