Italian Sausage Stuffed Shells

Preheat oven to 350 degrees F (175 degrees C). Lightly oil a 9x13 baking dish.

Bring a large pot of lightly salted water to a boil. Cook shells in the boiling water, stirring occasionally until tender yet firm to the bite, about 10 to 12 minutes. Drain. Lightly oil a rimmed baking sheet; place drained pasta on baking sheet to cool.

Heat 2 teaspoons vegetable oil over medium-high heat in a heavy skillet. Cook and crumble sausage until it has lost its pink color and begins to brown. Remove from heat; drain off grease. Stir 1/2 of the shredded cheese and Italian seasoning into browned sausage.
