I got this recipe off of Good Things Utah a long time ago. It's great--nice hearty, healthy hamburger patties, and if you're watching your carbs these are excellent by themselves with a little ketchup. I love them because they are very satisfying and always fill me up so I don't fill up on other junk!
1 lb. lean ground beef
1 c fresh spinach, chopped
2 T lowfat mexican blend shredded cheese
1/2 c chopped onions
1/2 c whole oats
Steak seasoning to taste
Salt & pepper to taste
-Fry onions with a little soy sauce then put in a big bowl with all other ingredients. Mix well. Shape into hamburger patties and grill.
