Place the ground brisket to a medium size mixing bowl.
Add the bread crumbs, egg, brown sugar, chili powder, ground mustard, ground cumin, salt, and liquid smoke. Stir until well combined. Easiest to completely mix with your hands.
Form the meat into meatballs by taking about 2-3 tablespoons of meat mixture and rolling between your hands to form a round ball shape. Set aside until all meat is formed into meatballs.
Heat the cooking oil in a large skillet over medium heat. Carefully add the meatballs and cook for about 2 minutes then carefully roll the balls. Continue until the meatballs are cooked and browned on all sides.
Remove the meatballs from the skillet and place on a plate. Pour out the grease from the pan and return to stove.
Add the ingredients for the sauce to the skillet. Stir to combine.
Carefully add the meatballs back to the skillet and simmer in the sauce for about 15-20 minutes while turning the meatballs about every 5 minutes to coat all sides.
Serve meatballs warm with sauce and enjoy!
