This recipe is actually my manicotti recipe...but I have been putting it in shells lately. Mostly because I noticed that you get more shells for your money! ; )
1 12 oz pkg of jumbo shells
4 cups cottage cheese (or ricotta)
2 cups grated cheese (cheddar or mozzarella)
1/2 cup parmesan cheese (I was all out--so it's not in any of my pics)
1 egg (I actually added 2 eggs...but I suggest only one)
1 T chopped fresh parsley
3/4 teaspoon oregano
1/2 tsp. salt
1/4 tsp. black pepper
Spinach--chopped--about 2 cups
garlic powder, onion powder, seasoning salt
3 cups (about 1 jar) spaghetti sauce
Heat oven to 375. Boil pasta according to directions and drain. Lay shells out on wax paper so they don't stick to each other.
In a 9X13 pan, spread about 1/2 cup spaghetti sauce.
Mix together all remaining ingredients (except spaghetti sauce).
I used 2 eggs, but it turned out a little bit runny...I don't know if that was because of the egg or because I used some fat free cottage cheese. I don't normally put any egg into my manicotti mixture...so you could just leave it out!
I always end up throwing some of these three into lots of things I make...just to season it up a little.
