Combine beef, onions, peppers and seasoning to your taste. Shape into 1-inch patties. Press your thumb in the middle to make an indentation, so the patties will even up as they shrink a little. Cook over a medium or medium-low heat 5 to 6 minutes each side, covered, on whatever you choose, grill, griddle, or skillet. We prefer ours medium well. The peppers and onions and ground beef keep the ground chuck from being dry and add a wonderful flavor. In last the last two minutes of cooking, shake sauce well and spoon on to burger. Add cheese, just long enough to melt.
