Make the marinated grilled chicken.
Slice the bread in a half and brush each side with olive oil. Pan fry the bread in a cast iron skillet (or grill) over medium heat.
Rub each side of the bread with half of a garlic clove.
Lather one half of the bread with pesto.
Layer the chicken, mozzarella, and tomatoes and drizzle with a little balsamic glaze.
Top with the other half of the bun. Enjoy!
