what i do with hamburger is make what i call 'moo moo mushroom goulash', lol.
hamburger
2 cans mushroom soup
whatever veggies you like - i tend to use peas and broccoli and zucchini most often
spices to taste - garlic powder, cracked black pepper, and the yellow container of mrs dash go good in this for me
cook up the hamburger all the way to done in a slow cooker on high (drain off the fat/oil if it isn't lean/extra lean beef), dump in your mushroom soup and veggies, cook on high for a bit longer until the soup is thinned out, then turn it on low and let it simmer for a couple hours. serve over rice or egg noodles or pasta.
even my kiddo loves it!
