01 - In a large bowl, whisk together the olive oil, soy sauce, balsamic vinegar, maple syrup, minced garlic, smoked paprika, salt, and pepper until well combined.
02 - Add the pineapple chunks, bell pepper, zucchini, red onion, and cherry tomatoes to the marinade. Toss thoroughly to coat all pieces evenly and let rest for at least 15 minutes.
03 - Thread the marinated pineapple and vegetables alternately onto skewers, distributing the ingredients evenly across each skewer.
04 - Preheat a grill or grill pan to medium-high heat, ensuring the grates are clean and lightly oiled to prevent sticking.
05 - Place the skewers on the grill and cook for 8 to 10 minutes, turning occasionally with tongs, until the vegetables are tender and lightly charred with grill marks.
06 - Remove the skewers from the grill and serve hot, optionally garnished with fresh herbs or a squeeze of lime juice.
