I'm sure that everyone has their own lasagna recipe, but I figured I would give mine :)
What you will need:
1 box lasagna noodles
1 pound hamburger
1 jar spaghetti sauce
1 container cottage cheese
1) Cook noodles as directly on package. Drain and lay on foil
2) While cooking noodles, brown and drain hamburger
3) Mix sauce and hamburger together in a bowl.
4) In a 9x13 casserole dish, make layers starting with the hamburger and sauce, then noodles, cottage cheese and then cheddar cheese. Repeat until you get to the top of the dish and then top with noodles and cheddar cheese.
