This is the recipe I grew up on. It's nice, I hear..., to not cook the noodles before hand. I wouldn't know. I don't bother with silly, time-wasting details like cooking lasagna noodles. :)
1 lb Ground beef
1 3lb bottle Prego
1 Large cottage cheese
2 Large balls of mozzarella, shredded
12 Lasagna noodles
Brown ground beef and mix with Prego. Spread 1/4 of Prego mixture on bottom of large cake pan. Place 4 noodles over sauce. Spread 1/3 of cottage cheese over noodles. Sprinkle 1/4 of the mozzarella over that. Repeat this layering process 2 more times. Top with remaining sauce. Bake at 350 for 45 minutes. Top with remaining cheese, bake 15 min. COOL!
