Instructions

1. 1
   Heat a large skillet over medium high heat. Add sausage and cook until browned, about 5 to 7 minutes.
2. 2
   Add tomatoes and about half a can of water. Decrease heat to low and let simmer for about 20 minutes.
3. 3
   Meanwhile, place spinach in a colander and pour hot water over spinach to wilt slightly. When cool enough to touch, squeeze out excess water.
4. 4
   Preheat oven to 400°F. Spread about a third of the tomato mixture in the bottom of a medium baking dish. Layer on a third of the spinach, a third of the ravioli and a third of the cheese. Repeat twice with the remaining ingredients.
5. 5
   Cover with foil and bake for 35 to 40 minutes or until lasagna is bubbling, removing foil during last 5 to 10 minutes of baking. Serve warm.
