Wow, Pinterest has really good recipes! This is my adaptation of another recipe I found on there. I have frozen half of these since this recipe makes way more than 2 people can eat. We'll see how the frozen ones turn out in a few weeks!
Spinach & Sausage Stuffed Pasta Shells
1 lb hot sausage, browned
1 tbsp minced garlic
1 c frozen spinach, cooked and drained
3/4 cup ricotta cheese
16-18 pasta shells, cooked and drained
1 cup mozzarella cheese
1 can diced tomatoes with basil and oregano
Brown sausage with garlic, drain. Cook shells according to package directions and drain. Add cooked shells to a bowl of ice water to cool. Return sausage to skillet, add tomatoes and spinach, heat for 2-3 minutes. Remove from heat and stir in ricotta. Stuff shells with a fork and place in a greased glass baking dish. Cover with mozzarella cheese. Bake at 350 degrees for 25-30 minutes.
