Set a rack about 6 inches from heat source and preheat broiler to high. Line a broiling pan with foil. (Alternatively, preheat a gas grill to medium-high.)
Thread pork, peppers and mango onto long metal skewers or wooden skewers that have been soaked in water, alternating ingredients.
Combine honey, soy sauce and lemon juice in a small bowl; stir to combine. Set aside 2 Tbsp. honey mixture.
Season kebabs with salt and pepper. Brush on all sides with honey mixture. Broil or grill, turning and brushing often with honey mixture, until lightly browned and pork is firm to the touch, 10 to 12 minutes. Using a clean brush, coat kebabs with reserved 2 Tbsp. honey mixture and serve.
