Preheat oven to 350
Put a large pot of salted water on the stove and bring to a boil.
In a large bowl combine cottage cheese, garlic, Parmesan cheese, egg, Italian seasoning, salt, and pepper. Mix thoroughly.
Add shells to boiling water and boil for 3-4 minutes (they will be very al dente)
Drain shells.
Pour enough pasta sauce in the bottom of a 13x9 inch pan to cover the bottom with about 1/4 inch of sauce.
Fill the shells with the cottage cheese filling and then line them up in the baking pan.
Cover the shells with more sauce, and top with shredded mozzarella.
Bake for about 25 minutes or until the cheese is melted and the sauce is nice and bubbly.
Serve!
