Add 1 ½ tbsp oil to a large skillet. Heat on medium-high. Once oil is hot, add your chicken pieces. Season with chili powder, salt, pepper, garlic powder, onion powder, cayenne pepper. Sauté for 3 to 4 minutes uncovered, flipping occasionally. Chicken should have some browning. Remove from skillet and set aside.
Add 2 tbsp oil to the skillet. Once the oil is hot, add the diced potatoes and onion. Sauté on medium-high heat, stirring occasionally until sides of potatoes have browned and onion and potatoes are fairly tender. This can take 5 to 10 minutes depending on your stove and the size of your potatoes.
Reduce heat to medium. Add chicken, tomatoes, green chiles, chicken stock, oregano, parsley, and salt to potatoes and onions. Stir. Cover and simmer for 5 minutes or until potatoes are done and everything is warmed through.
