3/4 pound shell pasta
1 cup greek yogurt
2 cloves garlic, finely chopped
Salt and black pepper
1 pinch cayenne pepper
3/4 pound sweet italian sausage, casings removed, meat torn into bite-size pieces
2 cups thawed frozen peas
1 tablespoon chopped fresh mint
In a large pot of boiling, salted water, cook the pasta until al dente, about 10 minutes. Drain, reserving 1 cup of the pasta cooking water.
Meanwhile, in a medium bowl, mix the yogurt and garlic; season with salt and the cayenne.
In a large nonstick skillet, cook the sausage over medium-high heat, stirring occasionally, until cooked through, 6 to 8 minutes. Add the peas and season with salt and black pepper. Cook until just heated through. Add the pasta and 1/2 cup of the reserved pasta water and toss, adding the remaining pasta water if needed to thin the sauce; season with salt and black pepper.
Divide the pasta among 4 bowls. Top with the yogurt mixture and mint.
