To toast seeds, in wide frying pan over medium heat, toast 1/2 cup sesame seeds, shaking pan until golden. Transfer to blender or motor and blend. Slice meat across grain 1/8 inch slices. In bowl, stir seeds, soy sauce, sugar, oil, garlic, ginger, and pepper. Combine with meat; cover and chill 1 to 1 1/2 hours. To cook, add 2 tablespoons salad oil to wok or heavy fry pan.
