This is one of those recipes where I don't read directions or follow measurements but here is my best guess:
Brown 1lb of hamburger, add seasoning salt
Add 1 can of spaghettti sauce, shredded cheddar cheese, parmesan cheese, and cottage cheese, mix together and heat through,
Cut off the tops of hard rolls and scoop out the middle. Fill rolls with filling and replace top. Cover with tin foil and bake 350 for 20 minutes or until roll is starting to get crunchy and filling is warm.
