• 4 tablespoons margarine or butter
• 4 large eggs
• 1 cup flour
• 1 cup whole milk
• 1 teaspoon salt
• 1 teaspoon baking powder
• 1 tablespoon onion, minced
• 1 pound medium sharp cheddar, shredded
• 2-10 ounce packages frozen spinach, thawed and well drained

Preheat oven to 350 degrees.  Melt the margarine or butter in a 9x13 inch baking dish in the oven.  While the margarine is melting beat the eggs in a bowl large enough to hold all ingredients.  Add the flour, milk, salt and baking powder and mix thoroughly.  Add cheese, spinach and onion and mix well.  Spoon into baking dish with the margarine and level off.

Bake for 35 minutes.  Remove and allow to cool before serving.
