Mix all of the ingredients together aside from the butter. Form the meat into medium sized meatballs. In a frying pan, heat your first tablespoon of butter. As it begins to foam, begin to add your first batch of meatballs to the pan, then using a potato masher smash the meatballs into flat patties. Allow the first side to brown, this will help you keep the shape. Then quickly flip the patty. It's okay if this side isn't perfectly browned. Lay these patties on a flat baking sheet.

Once you've made all your patties, broil them in the oven for about a minute on high to allow a good caramelization of the meat. If you are making just one or two patties you can skip this step, just cook it to whatever level of doneness you want. You can freeze the rest of the meat blend if you want to just make one or two.
