Heat the oil in a Dutch oven or large deep skillet. Saute the onion and garlic while you cut up the pork. Add the pork to the pan and brown, stirring now and then.

Add the rest of the ingredients, stir, bring to a simmer, cover partially, and simmer 2-3 hours. If it starts getting too dry, add more liquid. If there's too much liquid at the end, you can mix 1 Tbs cornstarch with 2 Tbs cold water, then stir that in and simmer a few minutes to thicken.
