Meat for the KIDS

QUICK AND EASY MEAT LASAGNA
My kids have been begging me for Meat Lasagna for weeks. So I decided to make it for them.
I buy market districts natural meats (ground beef) and mostly organic cheese - I buy it already shredded. I think a mix of cheeses taste best and I even like some cheddar and provolone mixed in(don't forget to add parmesan). I use oven-ready lasagna noodles (although as long as you have enough liquid any noodle can be used.)

1 med to lrg onion chopped
1-11/2lbs ground beef
8 oz box of fresh mushrooms chopped into small pieces
15ounce container ricotta cheese
Generous 6 ounces (or more) mixed cheeses
Arugula or spinach (uncooked, there's your xtra liquid)
1 box lasagna noodles
25 oz jar of your favorite tomato sauce. I used Muir Glen Vodka sauce.
Extra sauce from a new jar.

Cook the onions and beef in a pan until browned and set aside to cool after draining off grease.
Saute the mushrooms in the same pan(no need to clean but may need to add a little more oil if you poured out the grease from the meat) just till cooked and cool.
Mix your cheeses together in seperate bowl
Mix meat, sauce and mushrooms together.
Put a little of the extra sauce on the bottom of your 9X12 glass baking dish. Layer over with your uncooked lasagna noodles(you will have to break noodles to fit). Layer sparingly, just enough to cover noodles with spinach or arugula then with meat mixture, and then with cheese. Do this again starting with the noodles, spinach, meat and cheese. Top this with noodles and more of the extra tomato sauce. Sprinkle some extra cheese on top for good measure. Bake on 375 for about 1 hour. It should be bubbling and noodles easy to put a fork through.
Enjoy!
