For a little extra flavor cook hamburgers in an iron skillet.
In an iron skillet put couple tbs of olive oil to Sautee chopped onion ( yellow sweet onion is best) once onions are soft place hamburger patties on top on high heat sear both sides. Then add to your liking dales sauce, Worcestershire sauce and my secrete ingredient left over coffee from the coffee pot. Cook uncovered until most of the liquid is gone then cover with your favorite cheese and enjoy.
