Here is another recipe from my MIL. Also very good.

Mexican Lasagna

1/2 lb. ground beef
2 slices onion, choped
1/2 clove garlic, minced
3/4 cup cottage cheese
1/2 cup sour cream
1 tsp. cumin
1/8 tsp. salt
1 1/4 cups salsa
2 large whole wheat tortillas (use corn or other GF tortillas to make this GF)
3/4 cup shredded monterey jack or mozzarella cheese

Cook beef, onion and garlic in pan. Drain. Combine the cottage cheese, sour cream, cumin, and salt. Spread 1/2 cup of salsa across the bottom of an 8×8 baking dish. Place 1 tortilla over salsa. Spread half of cottage cheese mixture on top. Top with half of the beef. Top with 1/2 cup of salsa and 1/4 cup of cheese. Repeat layering – tortilla, cottage cheese, beef. Top with remaining salsa and cheese. Bake for 30 min. at 350.

*I think it would be good with some beans added to the cottage cheese mixture.
*It would probably work well to prep this ahead and either freeze it for later use or to bake later in the day.
