2 lbs. ground meat
3 egg whites
1 onion, diced
½-1 cup shredded green cabbage
2 tsp. salt
1 tsp. ground pepper
¼ c. dijon or other prepared mustard
2 c. breadcrumbs (can whirl some stale bread in the blender)
Preheat the oven to 375f. Grease a 9x13” pan if you like a thin meatloaf, or a more square/deep pan if you want leftovers shaped for sandwiches.
Mix together all ingredients so that everything is completely mixed; use your hands if you need to, or a big wooden spoon.
Pat everything evenly into the pan, and bake for an hour, or until the top of the meatloaf is golden brown. The loaf will shrink a bit, and it will look like it's kind of floating in juices. Just let it sit for about fifteen minutes when you remove it from the oven, so the juices can re-absorb.
Slice and enjoy!
