Easy 3-Layer Lasagna

My first time to make lasagna! It tastes much better than the frosen ones from store, because it's homemade. It's so simple to make and you can cook once and save for another meal. 

12 Barilla Lasagna noodles (I used the "no boiling required" noodle. If you use regular lasagna noodle, cook noodles according to package instruction.)
2 eggs,
15 oz ricotta cheese
2 cups mozzarella cheese
1/2 cup Parmesan cheese
1 Lb ground beef (cooked, drain)
5-6 cups fresh spinach leaves or canned leaf spinach (drain)
1 jar Italian sauce or pasta sauce

    Preheat oven to 375 degrees. Grease 9*13 baking pan.
    In a bowl beat eggs, stir in ricotta cheese, 1 cup of the mozzarella cheese and Parmesan cheese. Stir in spinach.
    Spoon 1/3 Italian sauceon bottom of the pan. Layer 4 noodles, half ricotta cheese mixture, and half amount of the meat. Then layer another 1/3 Italian sauce, 4 noodles, and the reamianing ricotta mixture, remaining meat. Layer last 4 noodles, remaining Italian sauce. Top with remaining mozzarella cheese.
    Cover with foil, bake for 50-60 minutes. Let stand for 10 minutes before serving.
    If you like veggetarian lasagna, just omit ground beef. Still yummy!
