Heat a small saucepan over medium heat. Add oil and onions and saute 5 minutes. Add vodka and boil to reduce by half. Add Worcestershire, hot sauce, tomato sauce and horseradish. Stir to combine the dipping sauce and return the sauce to a simmer. Add salt and pepper and adjust seasonings.
Heat nonstick skillet over high heat. Coat meat bites lightly in oil. Season with steak seasoning blend or salt and pepper, to taste. Cook the meat until caramelized all over, about 2 minutes on each side. Transfer dipping sauce to a small dish and place at the center of a serving platter. Surround the dip with meat bites and set several bamboo "stakes" or skewers alongside meat.
