Combine soy sauce, vinegar, lime juice, oils, garlic and pepper in a bowl. Add beef, stir to coat. Let sit at least 30 minutes, stirring occasionally. Thread beef cubes and peppers onto skewers. Start with peppers, using one of each color and alternate with beef. Place filled skewers on hot grill and cook about 12 minutes, until meat is done, turning over once.
