Preparation

Toast sesame seeds in a small frying pan over medium heat, shaking pan frequently until golden (about 3 minutes). In a bowl, mix sesame seeds, soy, ginger, garlic, sugar, vinegar, onions, cayenne and 1 T. of the oil. Add meat, stirring to coat. Cover and refrigerate for at least 2 hours or until the next day.
Heat 2 more T. of the oil in a wide frying pan over high heat. Add meat, half at a time, and cook, stirring, until done to your liking when cut (about 2 minutes for medium doneness). Repeat with remaining meat, adding remaining oil as needed.
Serve with toothpicks, or eat the mixture wrapped in lettuce leaves.
