Heat closed contact grill 5 minutes. In shallow nonmetal dish, mix taco seasoning mix, lime juice, chipotle chiles and honey. Add beef, bell pepper and onion; toss to coat.
When grill is heated, place beef and vegetables on bottom grill surface. Close grill; cook 4 to 6 minutes, turning mixture occasionally, until beef is desired doneness and vegetables are crisp-tender.
Spoon beef and vegetables evenly down center of each warm tortilla. Top with guacamole, sour cream, shredded lettuce and/or chopped tomatoes. Roll up each tortilla around filling.
