Dice the onions finely in a food processor. Saute the ground pork and diced onions together in a large skillet slicked with vegetable oil. Add the vinegar, Worcestershire, mustard, tomato sauce and 1 1/2 cups water. Bring to a boil and then simmer, uncovered, for at least 1 hour until thickened. Add black pepper and Texas Pete to taste--the hash should have a tangy bite and the black pepper should be pronounced. Serve over white rice.
