1 pound Summer squash
1/4 cup Butter
1/2 cup Chopped onion
1 Egg
1/2 cup Mayonnaise
Salt and pepper to taste
1/2 cup Shredded Cheddar cheese
1/2 cup whole wheat Bread crumbs

You don't need to peel the squash. Just slice them thinly and then steam or simmer in some water until soft.

Mix together the egg, onion, mayonnaise, cheese, salt and pepper. Add the squash and a few Tbs of butter and mix together. Pour into a small casserole dish, top with the breadcrumbs, and dot the rest of the butter.

Bake at 350 for 30 to 40 minutes.
