Combine sauces, vinegar, oil and ginger to make a marinade. Add lamb cubes and marinate 4+ hours or overnight in the fridge. Tip: Marinate in a ziplock bag and take with mangos and skewers to barbeque at a picnic.
Put wooden skewers in water to soak. Heat barbeque (or oven grill). Cube mangoes to same size as lamb cubes. Alternate lamb and mango cubes on skewers.
Grill over medium hot coals until lamb is tender and golden brown, basting with marinade as needed to keep moist.
Serves 4 as main course or use smaller cubes and amounts as appetizers.
Good served with pita bread, couscous or rice, salad and white wine.
