I have to make a lot for my crew so you might want to make a little less. I used:
1 package favorite type noodle (I used bowties)
1 container cottage or ricotta cheese
1 large hunk mozzarella, grated
about 3/4 C grated parmesan cheese
4 eggs
about 2 T parsley
pepper & salt to taste
2 lbs ground beef
Italian seasonings
Cook the noodles as directed on package.
Brown ground beef w/some onion, garlic, oregano, basil.
Mix together the cheeses, egg, parsley and salt and pepper
In a large bowl, stir together the browned ground beef, cheese mixture and cooked noodles.
dump the whole lot into a large rectangular baking pan and cover with foil.
Cook in 350 degree oven for 30-40 minutes.
For stage 2, pour spaghetti or tomato sauce on top and top w/ a bit of grated parmesan.
I also used the cheese mixture as stuffing for manicotti shells and spooned the ground beef around the shells in the pan.
