Ravioli with Bell Pepper Sauce

Put a large pot of lightly salted water on to boil for cooking ravioli. Heat oil in a large nonstick skillet over medium heat. Add garlic and 1 teaspoon rosemary; cook, stirring, until fragrant, about 1 minute. Add stir-fry vegetables and tomatoes. Bring to a simmer. Cook until vegetables are tender, 5 to 10 minutes. Stir in spinach; cook until tender, about 2 minutes more. Add the remaining 1 teaspoon rosemary and season with pepper. Meanwhile, cook ravioli in the boiling water until they float, 5 to 7 minutes. Drain and transfer to a large bowl. Toss with the sauce. Serve with Parmesan. Substitution: In place of the frozen stir-fry mixture, use 1 onion and 2 bell peppers, sliced.
