Spinach, Mushroom and Cheese Square
2 tablespoons butter, melted
1 cup all-purpose flour
1 cup milk
1 teaspoon baking powder
1 pound shredded Cheddar cheese (I use half Colby and cheddar)
1 (10 ounce) package frozen chopped spinach
1 small sweet or spanish onion finally chopped
8-10 mushrooms finally chopped (optional, my twist for this recipe)
Use a 9×13 glass pyrex, pour melted butter and distribute well.
1) Drain spinach very well until dry
2) Add all remaining ingredients into a medium size bowl.
3)mix well and pour into buttered pyrex.
2) Bake at 350 for 35-40 minutes or until brown and bubbly.
