I make this quite a bit, and it is usually without measurements, so I am going to give this a try, but you will have to guess and adjust as you see fit.
1 lb gr beef
1/2 lb ground sausage
1/2 box oven ready lasagna noodles
1 jar of your favorite spaghetti sauce
1 tub of cottage cheese (8oz I think)
Shredded Mozerella cheese
1/2cup parm (I use kraft, but I guess you could use fresh)
Brown your gr beef and sausage together, drain, add spaghetti sauce to it, let simmer. Mix 3 cheeses and egg. Put a thin layer of sauce in the bottom of the pan (I either use a 8x8 or 2 loaf pans). Start layering - noodles, meat, cheese. In the loaf pans, I can get 3 layers of noodles, meat and 2 of the cheese mixture, my top cheese layer is straight mozerella. Cover with foil - 350* for about 25 minutes, then uncover and put back in long enough for the cheese to brown.
