This is so fast and easy. 
My father-in-law LOVES my lasagna. 
Little does he know it's not really lasagna! :)

Lasagna noodles
1 cup shredded cheddar cheese
1 lb hamburger
1 jar Spaghetti Sauce - traditional is best.

Cook the lasagna noodles according to package directions.  Rinse, toss with a touch of oil so it won't stick together and cool.

Brown and drain the hamburger, crumbling it as you cook it. 

In a 13x9x2 pan, sprayed with non-stick spray, layer the 1/2 the noodles, 1/2 of the hamburger, 1/2 of the sauce and 1/2 of the cheese. Repeat and top with the cheese. 

Bake at 425 for approximately 30 minutes.
