Preheat oven to 400. I used convection. Line a baking sheet with foil. Add the mushrooms, pineapple, and ham onto the skewers in an alternating fashion and arrange them on the baking sheet. Coat with bbq sauce and bake until the corners on the cubed ham and or pineapple start to brown, about 15 minutes or so. Redress with bbq sauce and serve over rice.
