I used a 9x12 pan and made two rows of five pieces of lasagna that has been cut into 3 so that you will have five stacks on each side. Add some gravy then add green peppers and onions on top of each piece. Add the gravy and hamburg on top of the onions. I used cheddar cheese and guyere so I layered the cheese on top. Put a noodle on top of that and layer onions and peppers, hamburg and gravy and cheese. Add the top noodle and cover with hamburg and gravy and cheese.
