I found this recipe on the Texas Beef Council website. Don't let the name of the dipping sauce fool you - DH and I didn't find it fiery. Some people may find it a little spicy, but not fiery. Freezing the meat prior to slicing and using an electric knife makes this job much easier. The original recipe did not call for seasoning the meat before grilling, but we found it needed a little seasoning. We loved this recipe and it can be used as an appetizer or a main dish. The flavor is great. Please do not overcook or you will wind up with very tough pieces of meat. The preparation time includes the marinating time. This will serve 6 as an appetizer or 4 as a main dish.
