Diane's Lasagna

Aren't family recipes THE best?! Tried and true and tasty. This is Mike's mom's lasagna recipe and it was Delicious...my first ever lasanga attempt was a success! It makes A LOT of lasagna though, so be prepared. I used 3 separate 8x8 dishes, which worked out well for me (1 for Mike and the girls, 1 to share with a friend, and 1 using gluten free Penne noodles for me and Preston). If you don't have a humongo dish, I think a 9x13 and an 8x8 would do the trick.
Ingredients/Directions:

*Boil water for 1 lb pkg lasagna pasta noodles and cook as directed.

3/4 lb hamburger
3/4 lb Italian sausage
1 yellow onion, chopped
2-4 cloves garlic, minced
2-3 Tbsp dry basil leaves
2-3 Tbsp dry oregano leaves
1/2 bell pepper, chopped (I didn't have one on hand)
salt and pepper
*Mix all of the above and fry in a pan. Break up meat as it cooks so there aren't big chunks.

*Add:
10 large fresh mushrooms, sliced
2 pkgs spaghetti seasoning mix, Lawry's original is best (didn't have it at my store)
add the amount of water the seasoning mixes call for
2 6 oz cans tomato paste
1 28oz can diced tomatoes (I used 2 14 oz cans w/ garlic and onion in them)

*Simmer 20 minutes, stir occasionally
16oz cheddar cheese, grated
16oz mozzarella cheese, grated
24oz cottage cheese

*Assembly:
-Spread some meat sauce in bottom of pan to prevent noodles from sticking
-Cover the meat sauce on the bottom of the pan with a single layer of noodles
-spread half of meat sauce over pasta
-add another layer of pasta
-spread all of cottage cheese on pasta, sprinkle half of both cheeses over it
-add another layer of pasta
-spread remaining sauce and sprinkle remaining cheese on top

*Bake at 400 for 20-30 minutes, until hot in center.
