When I was much ,much younger Mom and Dad would take us to "Night in Old San Antonio" during fiesta week. There was a lot going on, music, and food, and unfortunately I was too young for the beer garden. One of the things I remember is some chunks of beef on a skewer. They were delicious! I remember them to be right off a charcoal grill and spicy hot. I have tried to make them a few times but they just don't seem right. Does anyone know about these things and more importantly how to make them?
