Spinach Squares

I think I made these at our very first meeting.

1 (10 oz.) package of frozen spinach
1 stick butter
3 eggs, beaten
1 cup milk
1/2 pound cheddar cheese, grated
1 cup flour
1 cup chopped onion
1 tsp. baking powder
1 tsp. salt
pepper
1/8 tsp. nutmeg

Preheat oven to 350 degrees.
Cook spinach according to package directions and drain well.
Melt butter in 9 by 13 baking pan. Combine remaining ingredients with spinach and mix well. Turn into pan, stirring in butter and spreading evenly. Bake 30 minutes. Cut into 1 1/2 inch squares to serve as an appetizer or 3 inch squares to serve as a side dish.

I want the recipe for that corn side dish Josh made when we were at Dara's house last time. Remember that?
