To assemble the skewers, cut the ham, onion, pepper, mushrooms and fresh pineapple into 1” cubes and thread onto metal or wood skewer sticks, alternating ingredients.
To make the grilling sauce, combine the pineapple juice, ketchup, soy sauce, garlic cloves and brown sugar in small sauce pan. Bring to a boil, then reduce heat to low and simmer for at least 10 minutes. Allow to cool before use.
Cover skewers with grilling sauce. This can be done ahead of time and then stored in the refrigerator, if needed.
To cook skewers, heat grill to medium-high and sear each side for about 5 minutes until all ingredients have been heated through and have nice sear marks.
Makes 10 skewers. Nutritional info based on one skewer.
