Way back in college, I stayed two summers to take classes. The first summer, I found a cheap apartment for the summer and lived by myself. My soon-to-be-husband came up, proud as can be because his mother taught him how to make lasagna. For me. Well, we still have the recipe. I made it just the other night, but made it the day before and it was fabulous.
Brown ground beef and onion. Add garlic, oregano, soup, water, and vinegar. Simmer ½ hour. Put some liquid in bottom of baking dish. Layer noodles, cottage cheese, ½ meat mix, noodles, mozzarella, rest of meat mix (or whatever comes out).
Bake at 350*F for 20 - 30 minutes.
If making ahead of time, refrigerate, then bake for one hour.
