Brown meat in oil in large stew pot.

Add all remaining ingredients (cut onions into large chunks 5x5).

Cook 2 hours covered on very low simmer. Remove lid, turn heat up and boil water out (approximately 1 hour more).

Stir and crush/shred meat throughout. You will probably find that the meat begins to fall apart after the first 1 to 1 1/2 hours making it easier to crush or get that shredded consistency. There should be no large lumps of meat. Make sure that it is completely shredded/crushed.

To serve: Heat flour tortillas in light oil in fry pan. Place meat mixture in tortilla. Roll and serve 2-3 tortillas per person. Eat alone or with mexican rice and refried beans if desired.
