• Preheat oven to 375F.
• Bring a large pan to medium high heat, add vegetable oil to lightly coat the bottom of the pan.  
• Add beef, sausage, and onions.  Cook ~ 8-10 minutes or until meat is cooked through and broken apart.
• Add garlic and cook 1-2 minutes or until fragrant.  
• Add crushed tomatoes.  Bring to a boil, reduce heat, and simmer uncovered ~ 30 minutes.  Add salt to taste.
• Mix together ricotta cheese and egg.

Get ready to put it together:

• Spread a light layer of meat sauce (~2 cups) in the bottom of a ~9x12 baking dish and add:
• 4 noodles
• 1/2 of Ricotta Mixture
• 1/3 of Mozzarella Cheese
• 1/3 of Parmesan Cheese
• add another 2 cups of meat sauce.  Repeat.
• You will end this with a layer of noodles, sauce, mozzarella, and Parmesan (no Ricotta in the final layer).  Tuck in any noodles on the side into the pan and sauce.
• Cover with lid or lightly spray oil on a piece of aluminum foil (this prevents the cheese from sticking).  Bake covered (try not to let the foil touch the cheese) for ~20 minutes covered.  
• Remove lid or foil and bake another 20 minutes or until cheese is browned.  If cheese is not browned, you can put on the broiler for 2-3 minutes but be careful not to burn the top.  
• Let rest 30 minutes before serving (I know it's hard!).  Happy Eating!  Beckie
• Please note: You will have 2 cups of pasta sauce leftover.  Freeze it and add pasta later.
