Stuffed Shells

Jumbo Pasta shells ( a pakage usually has 25 in it)
Salt and pepper
1 lb ground beef
1 lg onion, diced
1 frozen package spinach, thawed and "wrung" out ( I squeeze it in a papertowel)
1 jar sauce, we have used Spaghetti sauce and Alfredo
Boil shells according to package. I add in a little vegetable oil to prevent sticking.Drain and rinse shells until cooled. In a large skillet, cook onion and ground beef, seasoning with salt and peper. Drain. Stir in spinach. Stuff shells with about a 1 in ball of filling. Place in 9x13 pan, touching is ok. Pour sauce over top. bake on 350 for 25 minutes.
* I have also topped with shredded cheese prior to baking*
This is a good potluck dish, too!
