01 - Soak wooden skewers in water for 20 minutes to prevent burning during grilling.
02 - In a small bowl, combine the melted butter, minced garlic, chopped parsley, salt, and black pepper. Stir until well blended.
03 - Arrange zucchini rounds and red bell pepper pieces alternately onto the skewers, leaving a small gap between each piece for even cooking.
04 - Brush the vegetables generously with the garlic butter mixture, reserving a portion for basting during grilling.
05 - Preheat an outdoor grill or grill pan to medium-high heat.
06 - Place skewers on the grill and cook for 3 to 5 minutes per side until tender with light char marks, brushing occasionally with the remaining garlic butter.
07 - Serve immediately, garnished with extra parsley and a squeeze of fresh lemon juice if desired.
