It may look like a sad little package shoved in the back of your freezer, but frozen spinach actually has a lot of culinary uses (and some may surprise you).

The four different cheeses in this mac and cheese recipe add a delicious depth of flavor that you don't get in other recipes.

1/2 package (8 ounce size) elbow macaroni
1 cup shredded sharp Cheddar cheese
1 cup shredded provolone cheese
1 cup shredded Mozzarella cheese
1 cup shredded Colby-Monterey Jack cheese
1 egg, beaten
1 cup milk
Preheat oven to 350 degrees F. Lightly grease an 8x8 inch baking dish.
Cook macaroni according to package directions; drain and set aside.
Sprinkle the Cheddar over the bottom of the greased baking dish. Top with 1/4 of the pasta. Sprinkle with the Provolone and then top with another 1/4rd of the pasta. Top with the Mozzarella and the remaining pasta. Top all with the Colby-Jack cheese.
In a small bowl or measuring cup, whisk together the egg and milk until frothy and combined. Pour over the pasta in the baking dish.
Place the baking dish in the oven and bake at 350 degrees F for 30 minutes or until set.
Serve the four cheese macaroni and cheese hot.

A can of cream of mushroom soup can be a real dinner saver. It works great in casseroles and can turn into a sauce or gravy in a pinch.
Pizza night is always a favorite, especially when you have great tasting pizza from some of the most popular restaurants.
