Stuffed Shells

This is one of the few recipes in which all my kids eat the meat AND the spinach in the dish. It is a nice variation when you are tired of spaghetti.

1 box jumbo pasta shells
1 pound ground beef
2 TB olive oil
6 oz baby spinach, chopped
1 cup chopped onion
1 garlic clove, minced
1 tsp salt
1/4 tsp pepper
1/8 tsp nutmeg
1 egg
1/4 cup Parmesan cheese
1 jar of spaghetti sauce
1 cup mozzarella cheese

• Cook shells according to directions, reserving 1/3 cup of the water.
• Cook ground beef until no longer pink and drain grease.
• Add oil, spinach, onion, garlic, reserved pasta water. Continue cooking for 10 more minutes. Remove from heat.
• Add seasonings and blend well. Let mixture cool.
• Stir in egg and Parmesan cheese.
• Pour 1 cup of the spaghetti sauce into the bottom of a 9X13 pan. Fill the shells with the meat mixture and place in the pan. Pour remaining sauce over shells and sprinkle with the mozzarella cheese. 
• Cover with foil and bake for 30 minutes at 350 degrees.
