Preheat the grill or the oven to 450 F.

Prepare the veggies and pineapple by dicing them roughly the same size, in about 1-inch pieces. Slice the mushrooms in half.

Make the sauce by mixing the pineapple juice, and the Tabasco sauce with the packet of BBQ sauce and dry rub. Place the chicken cubes into a bowl and mix them with half the sauce. Do not marinate the chicken in the sauce. Use immediately. Pineapple makes chicken mushy very quickly.

Assemble the skewers by placing half a mushroom, three pieces of red onion, one piece of bell pepper, one pineapple piece, and one chicken cube. Repeat this two more times until the skewer is full. Do not overfill the skewer or the chicken will not cook properly. Brush the skewers with the remaining sauce. Season with salt and pepper.

Place the skewers on the hot grill and cook for 5-8 minutes on each side or until the chicken is cooked through.
