Preheat your skillet or toaster oven to medium heat, about 350°F. Slice the ciabatta lengthwise, creating a pocket for fillings. Brush olive oil on both sides to ensure a crispy exterior when toasted.
Spread garlic aioli on one half and drizzle balsamic glaze or pesto on the other. This creates a creamy, tangy base that makes every bite flavorful.
Layer your choice of grilled chicken or turkey on the aioli side. Top with mozzarella or brie cheese and, if desired, briefly broil for melty perfection.
Add roasted red bell peppers, arugula, and optional caramelized onions. These fresh ingredients provide crunch, color, and balanced flavor.
Place the top half of the ciabatta on the fillings and press gently. Slice diagonally for a beautiful presentation and serve immediately
