Spinach-Feta Casserole

2 (10 ounce) packages frozen chopped spinach

8 ounces crumbled feta cheese

2 cups shredded mozzarella cheese

1 cup cubed processed cheese food

1 cup melted butter, divided

2 tablespoons distilled white vinegar

½ teaspoon garlic powder

salt and pepper to taste

1 (16 ounce) package phyllo dough

Preheat oven to 425 degrees F (220 degrees C).

In a large bowl, combine the spinach, feta cheese, mozzarella cheese, processed cheese food, 1/2 the butter, vinegar, garlic powder, salt and pepper. Mix well and set aside.

Place a layer of phyllo dough into the bottom of a lightly greased 2-quart casserole dish. Spread the spinach and cheese mixture into the dish and top with 4 layers of phyllo dough, spraying each layer with butter-flavored cooking spray. Drizzle the remaining butter over the top.

Bake at 425 degrees F (220 degrees C) for 20 minutes.
