This is very popular in our house. The kids love the strips they can eat with their fingers and dip into the gravy. They prefer to have french fries with this so they can dip them in the gravy, too. Most definitely a Texas (or Oklahoma) recipe - Southwestern U.S.
NOTE: Although this isn't a low fat recipe, it doesn't contain anywhere near the amount indicated in the nutrition facts which include all the oil. If the oil is hot enough when you add the steak strips, it will absorb very little oil. Also, you can drain the cooked steak strips on paper towels to absorb more fat.
This is from Taste of Home. It has only four ingredients, and they all go into the crockpot at once. The meat is nicely seasoned and makes its own gravy. It tastes wonderful when you serve it over mashed potatoes.
