Pork Tinga with Potatoes

1 T. olive oil
1 lb. lean, boneless pork shoulder, trimmed and cut into 1.5" cubes
4 oz. chorizo sausage, casing removed
3/4 lb. red-skinned potatoes, quartered
1 large white onion, sliced 1/4" thick
1 garlic cloved, minced
28 oz. fire-roasted diced tomatoes, in juice
2-3 canned chipotle chiles en adobo, finely chopped
4 t. chipotle canning sauce
1 T. Worcestershire sauce
1/2 t. dried oregano, preferably Mexican
1/2 c. Mexican queso fresco
1 avocado, diced
warm corn tortillas

Heat oil in a large non-stick skillet. Once the oil is very hot, add the pork and chorizo in a single layer and cook, stirring until the meat has browned, about 6 to 8 minutes.

Add the meat and its juices, potatoes, onion, garlic, tomatoes with their liquid, chipotles, chipotle sauce, Worcestershire sauce, oregano, and 1/2 t. salt and stir to a slow cooker, and stir to mix thoroughly. Cook on high for 6 hours.

Gently stir, thin if needed with water, season with salt if needed. Scoop into a large bowl, sprinkle with the fresh cheese and avocado, and serve with warm tortillas.
