1 pound uncooked shrimp (31-40 per pound), peeled and deveined
3 garlic cloves, minced
1/2 cup dried cranberries
1/2 cup dry white wine or reduced-sodium chicken broth
6 ounces fresh baby spinach (about 3 cups)
4 ounces reduced-fat cream cheese, cubed
1/2 cup crumbled Gorgonzola cheese
3 tablespoons minced fresh parsley
1/4 teaspoon salt
1/3 cup chopped walnuts
Cook penne according to package directions for al dente. Meanwhile, in a large cast-iron skillet or Dutch oven, heat oil over medium heat. Add shrimp and garlic; cook until shrimp are pink, 5-10 minutes. Remove from pan and keep warm.
Stir cranberries and wine into same pan. Bring to a boil; cook until liquid is almost evaporated, about 5 minutes.
Drain penne, reserving 1 cup pasta water; add penne to pan. Stir in spinach, cream cheese, Gorgonzola cheese, parsley, salt and shrimp. Cook, stirring, until mixture is heated through and cheeses have melted, about 5 minutes, adding enough reserved pasta water to reach desired consistency. Top with chopped walnuts.
