I don't have a recipe, but if I remember right, what makes them tasty is some kind of smoky meat flavor. You could try bacon, a lot of it, with some of the drippings, as I have seen that in recipes.
Cook the hell out of the pinto beans, like you do for red beans, using broth or beer with onions, garlic, bell pepper, jalepeno and salt. Maybe a sprinkle of chili powder for a hint of that flavor.
Optional garnishes: green onion, chopped cilantro, jack cheese
