For the Chicken:

1. First, decide how you want to marinate your chicken.  We recommend this Simple & Delicious Chicken Marinade .
2. Prepare the chicken breasts by trimming any fat and then rinsing them.  Pat them dry and slice lengthwise, on a diagonal, creating two smaller pieces with even thickness out of each breast. Do this with both chicken breasts; you will have 4 roughly evenly-sized pieces.
3. Marinate them for 30 minutes to 24 hours ahead of time.

For the Bruschetta:

1. Next, prepare the fresh bruschetta.
2. Chop 2 Roma tomatoes.
3. Wash and pat the basil dry. Julienne basil leaves to equal about 2 heaping tablespoons.
4. Peel and mince 2 cloves of garlic.
5. Combine these ingredients in a small bowl and add 1 tablespoon of olive oil.
6. Add salt and pepper to taste.  Stir to combine
7. Now, set the bruschetta aside.

Assembling the Sandwiches

1. Heat your grill to medium heat and grill the marinated breasts, for about 4-5 minutes per side, depending on the thickness of the breasts. The internal temperature of the chicken should be 165° when done.  If you are new to grilling, see this post on Grilling for Beginners for some tips.
2. While grilling the breasts, you can prepare the buns or bread by slicing them and placing the bottom halves on a baking sheet a few inches apart.
3. Next, heat the oven to 400°.
4. When each breast is finished grilling, place it on each bottom bun/ piece of bread.
5. Then add 2 spoonfuls of bruschetta to the top of each breast.
6. Sprinkle the desired amount of mozzarella on top of each pile of bruschetta.
7. Bake in the oven for approximately 5 minutes, or until cheese is melted.
8. Remove the baking sheet from the oven, drizzle balsamic glaze on top, and top with the other side of the bun.
