4 tbsp. butter
3 eggs

1 c. milk
1 tsp. salt
1 tsp. baking powder
1 lb. grated extra sharp Cheddar cheese
2 pkg. frozen, chopped spinach, thawed and drained

Seasoned salt on top (optional)

Melt butter in 9x13 inch pan. In large bowl, beat eggs, add flour, milk, salt, and baking powder. Mix well. Add cheese, spinach, and onion. Mix well. Pour in pan. Bake at 350 degrees for 35 minutes. Serve warm for best flavor, but cold is okay, too! Cut in squares.
