Start by soaking 8 wooden skewers in water for at least 30 minutes to avoid burning on the grill.
In a medium saucepan over medium-high heat, mix the pineapple juice, soy sauce, olive oil, apple cider vinegar, brown sugar, ginger, and garlic. Stir frequently until the glaze reduces by half, making it thicker.
While the glaze cooks, prepare the peppers, pineapple, and onion by cutting them into 1-inch pieces. Follow the package instructions to cook the tater tots.
Preheat your grill to medium-high heat. Thread the ham, pineapple, and veggies onto the soaked skewers, alternating pieces. Don't pack them too tightly.
To prevent sticking, use tongs to hold a paper towel dipped in oil and rub it across the grill grates.
Place the skewers on the hot grill and cook each side for 2 to 3 minutes, until golden and charred. Brush the kabobs with the glaze as they cook, turning them to coat each side.
Once grilled to perfection, remove the kabobs and serve them hot with crispy tater tots. Enjoy!
