I work with a guy that grew up and went to school in the Springfield area. Always talks about Mexican Villa sauce. I think he gets the hot sauce. His son goes to school down there now -- at the end of the semester he brought up a bunch.
There's a Mexican restaurant near where I work that I go to for lunch. At it's best, the food is excellent -- but it's really inconsistent. When it's not at its best, its still pretty good. Rally good salsa, but, to my tastes, they overcook their chips. I like the people too. I ate there yesterday, and asked the guy how they season their taco/enchilada beef because I like it a lot. Hard to describe, but it's not like the store-bought seasoning packets that give you a gloopy mess that you can't even tell is beef. Here's what he told me he uses: Paprika, salt, garlic powder, black pepper, cumin. They cook it in water, which is how I always do it, rather than browning it. I took a crack at it last night, using about a teaspoon of everything, except ½ teaspoon of pepper. It was pretty close. Something to start from, anyway.
