I used a cast iron skillet and browned the hamburger. Remove the hamburger from the skillet, drain the grease and wipe out the skillet.
Pour half the pasta sauce into the bottom of the skillet.
Place half of the ravioli on top of the pasta sauce.
Place half of the hamburger on top of the ravioli.
Place half the cheese on top of the hamburger.
Repeat with second layer.
Pre-heat oven to 350 degrees. Bake for 30 minutes. Remove from oven and serve straight from your cast iron skillet.
ENJOY!
