You can cook your own chicken, but why not buy one of the cooked ones at the store?
Stock: cut meat off of the chicken and set it aside
Cook the rest of the chicken until the meat falls off of the bones. Take out all bones and skin from the pan.
In the Cuisinart blend: fresh garlic, cilantro, 4-6 tomatios, a few jalapeños, half an onion, a little salt, and cumin.
Add this to your stock as well as returning the chicken meat. Add 2 cans of hominy. Cook for about an hour.
Served well with fry bread!
