Ingredients

1 zucchini, thinly sliced
1 large tomato, thinly sliced
1 onion, thinly sliced
1/2 cup unsalted butter
1/4 cup red wine vinegar
1 teaspoon garlic salt
1 teaspoon dried basil
1/2 teaspoon dry mustard
2 cups grated Parmesan cheese

Preheat an oven to 350 degrees F (175 degrees C). Grease a 2-quart baking dish.
