Heat a 12-quart heavy stockpot and add the oil. Saute the pork, beef,
onions, garlic, cumin seeds, chili powder and bay leaves until the
meat is barely browned and the onions clear. Drain the fat and
discard. Add the remaining ingredients and bring to a simmer. Cook,
covered, for 1 1/2 hours. You may need to add water to the dish as it
cooks. The additional condiments that you may want are cooked
spaghetti, grated Cheddar cheese and chopped onions.
