I know this recipe is a bit off topic but I had a box of jumbo shells in my pantry that I've been wanting to make so I searched for a recipe and found this one from Cooking Light Magazine. It is really tasty. I used all the shells in the box rather than just making 24. I also used the entire container of part-skim ricotta. The only change you will need to make is to keep it in the oven longer. I left it in there for an hour rather than 30 minutes and it came out great. I also put shredded mozzarella on top.
I also found another recipe by Rachel Ray that I will try in the near future. Rachel Ray's recipes are far from "light" but usually really yummy.

Serves: 4 servings
8 pieces jumbo pasta shells
1 1/2 pounds ricotta cheese or part skim ricotta cheese
1 pound mozzarella, diced
1/2 cup grated Parmigiano-Reggiano
1 cup shredded Asiago
1/4 cup chopped flat-leaf parsley
2 tablespoons extra-virgin olive oil, 2 turns of the pan
3 cloves garlic, chopped
1 small onion, finely chopped
1 can (28 ounces) crushed tomatoes
Salt and freshly ground black pepper
6 or 7 leaves fresh basil, torn or shredded
Preheat oven or broiler to 450 degrees F.
Bring a large pot of water to a boil. Salt water and add pasta. Cook shells 12 to 15 minutes, they should be softened but still undercooked at the center. Drain pasta and cool.
Combine ricotta, 1/2 of the diced mozzarella, a couple of handfuls of Parmigiano and 1/2 of the Asiago. Add parsley to the cheeses and stir to combine.
To a small saucepan over moderate heat add oil, garlic and onions. Saute onions and garlic 5 minutes. Add tomatoes and season sauce with salt and pepper. Simmer sauce 5 minutes and stir in basil leaves
Pour a little sauce into the bottom of a shallow medium sized casserole dish. Fill shells with rounded spoonfuls of cheese mixture and arrange them seam side down in casserole dish. Top shells with remaining sauce and remaining mozzarella and Asiago cheeses. Place shells in very hot oven or 8 inches from hot broiler and cook 6 to 8 minutes to melt cheeses and bubble sauce.
