How to Make It
Preheat oven to 350°.
Cook pasta in boiling water until almost al dente. Drain. Combine pasta and beans in a large bowl.
Heat a large skillet over medium heat. Add oil to pan; swirl to coat. Add onion, garlic, and mushrooms to pan; cook 11 minutes or until liquid almost evaporates. Add turkey; cook 5 minutes or until done, stirring to crumble. Add bell pepper and next 7 ingredients (through red pepper); cook 1 minute. Stir in marinara sauce; bring to a boil. Add marinara mixture to pasta mixture; toss to coat. Divide mixture evenly between 2 (2-quart) glass baking dishes coated with cooking spray. Top evenly with cheese. Bake at 350° for 10 minutes or until cheese melts, or follow freezing instructions.
