4 oz. butter
3 eggs
1 c. flour
1 c. milk
1 tsp. salt
1 tsp. baking powder
1 lb. Monterey Jack cheese, grated
4 c. chopped fresh spinach

I use butter and frozen spinach.

40 squares.

Melt butter in a 9 x 13 inch pan. Beat eggs. Add flour, milk, salt and baking powder. Add cheese and spinach, mixing well. Spread into pan and bake at 350 degrees for 35 minutes. Cool 30 minutes before serving, cut into squares. These freeze well.
