My recipe:
1.5 lbs of 90/10 lean ground beef .75 c oatmeal .75 c chopped onion 1 extra large beaten egg 1 tbsp worchestershire sauce 3-4 chopped garlic cloves .5 tsp salt .5 tsp black pepper I bake at 350 F until thermometer reads 170 F and let it rest in pan for 10 minutes before plating and slicing but even with a super sharp knife it falls apart.
