Mushroom Pasta

Thanks to some bloggy friends who shared some dinner ideas! This one is from Tania

1 medium onion
1 lb ground beef
1 (1lb) box of rigatoni pasta
3 cans cream of mushroom soup w/ 5 cans of
water added
seasoning to taste (salt, pepper)
(I will also add crushed garlic and diced mushrooms for extra flavor. But this is not necessary to originally recipe.)
Saute onion and add ground beef until browned; drain excess fat if desired. Add remaining ingredients and stir well. Cook until most of liquid is very thick/almost gone; roughly 45 minutes.
Sounds great! I can’t wait to try it.
