Preheat oven to 400F.
Bring a large pot of salted water to a boil. Add the pasta to cook until al dente, or 1 minute under the package directions. Drain and toss in olive oil.
In an oven-safe skillet, add the olive oil to heat up for 1 minute.
Add the ground sausage to cook until browned, using a wooden spoon to break up the meat, about 6-8 minutes.
Transfer the browned sausage to a bowl. Add the ricotta and chopped basil to mix well. Season with salt and black pepper to taste.
Either transfer the mixture to a piping bag or spoon into the centers of each cooked pasta shell.
Add the marinara sauce to the bottom of the same skillet used for the sausage, then layer the stuffed pasta shells on top.
Top with the grated mozzarella to bake 15-20 minutes, until cheese is melted and slightly golden on top.
Garnish with freshly grated parmesan and enjoy warm with BUBBL’R lemon lime twist’r for a complimentary drink!
