Inside Out Ravioli

Fill a large pot with lightly salted water and bring to a rolling boil. Stir in pasta and return to a boil. Cook pasta uncovered, stirring occasionally, until tender yet firm to the bite, 8 to 12 minutes. Drain well.

Meanwhile, cook spinach according to package directions.

Meanwhile, brown ground beef, onion, and garlic in a large skillet over medium heat. Stir in spaghetti sauce, tomato sauce, and tomato paste; simmer for 10 minutes.
