01 - In a large mixing bowl, whisk together the olive oil, tamari, balsamic vinegar, maple syrup, minced garlic, smoked paprika, salt, and pepper until well combined.
02 - Add the pineapple chunks, bell pepper pieces, zucchini rounds, red onion wedges, and cherry tomatoes to the marinade. Toss thoroughly to ensure even coating 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, approximately 400°F, ensuring the grates are clean and lightly oiled.
05 - Place the skewers on the hot grill and cook for 8 to 10 minutes, turning every 2 to 3 minutes with tongs, until the vegetables are tender and have light char marks.
06 - Remove the skewers from the grill and serve immediately, garnished with fresh herbs or a squeeze of lime juice if desired.
