Heat the extra-virgin olive oil, a turn of the pan, in a deep skillet over medium-high heat. Add meat and crumble as it browns. Add chopped hot dogs after 3 to 4 minutes then cook 3 to 4 minutes more. Add the onions to the pan and cook to soften, 5 to 6 minutes more. In a bowl mix the spices, sugar, Worcestershire and tomato sauce. Pour sauce over the meat and simmer a few minutes to combine flavors. Slop onto buns and serve.
