This was yummy and a hit tonight with friends. I got the recipe off the back of the box of shells. I ended up using just half the box of shells- I now have some to use for another recipe :) I didn't have any spinach- so I just cooked the ground beef with the onion and garlic for 5 min. and didn't add any water. I didn't have any parmigiano cheese, so I used 1/4 c. of Parmesan and 1/4 mozzarella mixed together for the filling. This is an easy recipe to adjust to what is on hand.
1 box jumbo shells pasta
1 lb. ground beef
2 Tbs extra virgin olive oil
1 bag (6oz) baby spinach
1 cup finely diced onion
1 clove garlic, minced
1 tsp salt
1/4 tsp ground black pepper
1/8 tsp nutmeg
1/4 cup Parmigiano cheese
1 jar sauce
1 cup shredded mozzarella
PREHEAT oven to 350
COOK jumbo shells according to directions: drain, reserving 1/3 cup of the cooking water
COOK ground beef in large skillet until meat is no longer pink. Drain grease.
ADD oil, spinach, onion, garlic and reserved pasta water. Continue cooking 10min, stirring occasionally. Remove from heat.
