Here's another recipe that Weight Watcher's Core Plan approved.
1.5 lbs extra lean hamburger
1/2 c. oatmeal
1 egg
1T. Italian seasoning (I used Tuscan Marinara by Playful Palate)
Mush together like you would a meat loaf, then divide into patties. (I got 6 patties.) We had them with mashed potatoes and a side of sweet onions.
