Yellow Squash Casserole

4 (or more)  cups sliced yellow squash
1/2 cup chopped onion
35 butter crackers such as Ritz brand-( 1 stack)
1 cup shredded Cheddar cheese
2 eggs , beaten
3/4 cup milk
1/4 cup butter, melted (1/2  stick)
1 tsp. salt
pepper to taste
2 Tbls. butter

  Preheat oven to 400 degrees
Place squash and onion in a pan or skillet in a small amount of water and cook until squash and onion are just tender, about 5 min. Drain well.
In a medium bowl, mix together cracker crumbs and cheddar cheese. Stir half of the cracker mixture into the cooked wquash and onions.
In a small bowl, mix together beaten eggs and milk. Stir egg mixture into squash mixture, followed by 1/4 cup melted butter, salt and pepper. Mix well, the spread into a 9x13 baking dish. Cover top with remaining cheese and cracker mixture. Dot with 2 Tbsp. Butter.
Bake in preheated oven for 25 minutes, or until heated through and browned on top.

Tip: To make this dish low-fat , use low fat butter or margarine,  low fat crackers, and fat-free milk. It will still be just as tasty, I have made it both ways and can't tell any differences.
Also you can add more squash if you want to, Sometimes I add some Zucchini and it makes a very pretty casserole.
  This is one of my favorite casseroles and is even better tasting  the second day. Just reheat in the Micro.
