Assemble the skewers by alternating folded ham, pineapple, bell pepper, zucchini, and mushrooms. Brush the skewers with the BBQ sauce and let marinate (at least 5 minutes).
Preheat grill to medium-high heat and grill for 5-10 minutes until slightly caramelized.
Recipe Notes
If using store-bought BBQ sauce, make sure it has less than 7 grams of sugar per serving.
