After meat is thoroughly cooked and potatoes are about done (my grandma always made sure that some of the potatoes were fried w/ some crisp ones). Add meat to potatoes along with the tomatoes, tomatoe sauce, green chili, water. Heat should be about medium.
Then season with more salt, pepper, garlic salt, oregano and cumin (cumino)all to taste. My grandma never measured a thing. LOL simmer for about 20-30 mins. We always eat it with home made tortillas.
