Mix vinegars, honey, oil, and onions in a flat dish. Add chicken and mushrooms, cover, and place in refrigerator for an hour to marinate.
Preheat grill on high heat.
Remove mixture from fridge. Wrap the half slices of bacon around the chicken, and thread onto skewers, making sure bacon is secure. Alternate with pieces of pineapple and mushrooms.
Lightly oil grill grate. Place skewers on the grill. Grill skewers for about 20 minutes, brushing occasionally with additional marinade. They are done when bacon is crisp and juices run clear.
These are a big crowd pleaser, and even people who don’t think they like mushrooms will love these!
Tip from Administration: If using wooden skewers, soak them in water for 30 minutes before adding the foods and grilling them; this will prevent your wooden skewers from catching fire or burning.
