Slice each tomato removing both ends to be about 1/4 to 1/2 inch. Then do the same with the zucchini. Alternate zucchini and tomatoes around the dish and into the middle.

Melt butter and combine with bread crumbs and Parmesan. Sprinkle evenly over tomatoes and zucchini.

Bake for about 25-30 minutes or until topping golden brown.
