2 c. chopped zucchini
1 c. chopped tomato
1/2 c. chopped onion
1/3 c. grated Parmesan cheese
1 1/2 c milk
3/4 c. Bisquick baking mix
3 eggs
1/2 tsp. salt
1/4 tsp. pepper

Heat oven to 400 degrees. Grease 10" quiche dish or pie plate, 10" x 1 1/2". Sprinkle zucchini, tomato, onion and cheese in dish. Beat remaining ingredients until smooth.
