Cool the chicken: Heat the olive oil in a skillet over medium-high heat. Cook the chicken breasts until cooked through and golden brown on both sides, about 5-7 minutes per side. Let cool slightly.
Assemble the sandwiches: Slice the focaccia in half. Put chicken on bottom half. Top with a slice of prosciutto and 2 slices of mozzarella cheese.
Toast and serve: Place the sandwiches (still open) in the oven until the cheese is melted and the bread is toasted (about 5-10 minutes). Drizzle with balsamic glaze, close sandwich, and serve immediately.
Optional additions:
Add a layer of fresh basil or arugula for extra flavor and texture
Avocado: Adds a creamy texture and a healthy dose of fats
Tomato: Adds a juicy sweetness and acidity.
Roasted red peppers: Adds a smoky sweetness and a bit of heat.
Grilled zucchini or eggplant: Adds a light, summery flavor.
