Stuffed Jumbo Shells

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
