Bring a large pot of salted water to a boil.

Add orecchiette pasta and cook according to package directions until al dente.

While the pasta is cooking, remove the casings from the turkey sausage.

In a large skillet, cook the sausage over medium heat, breaking it up with a spoon.

Add the chopped onion and minced garlic to the skillet and cook until softened, about 3-5 minutes.

Stir in the crushed red pepper flakes.

Add the fresh spinach, Asiago cheese, Parmesan cheese, cannellini beans, and chopped roasted sweet red pepper to the skillet.

Season with Italian seasoning.

Cook, stirring occasionally, until the spinach is wilted, about 2-3 minutes.

Drain the cooked orecchiette pasta.

Add the drained pasta to the skillet with the sausage and spinach mixture.

Toss to combine.

Serve immediately, sprinkled with additional Asiago cheese if desired.
