Grilled Chicken Burger on Ciabatta

I find myself making more sandwiches these days and they're just so good and usually healthy. The ciabatta roll gives this chicken sandwich a more rustic taste and red onion really takes it to the next level. I like to serve with a simple salad for a complete meal.

Ingredients:
Grilled chicken breasts
4 cloves garlic
Romaine lettuce
Red onion
Ciabatta bread roll
Mayo
Stone ground mustard

Preparation:
Take your chicken breast and cut it in half to make it twice as thin. Then take a large piece of wax paper and set the 1 of the pieces chicken on it. Fold the wax paper over the top and pound the chichen breast so it's about 1/2" thick. Repeat the process for the remaining pieces.
 

Crush the garlic and spread some on each piece of chicken. Stack all the pieces together and place in a large zip lock bag to marinate for at least 1 hour.
 

Grill your chicken over high heat which should only take a couple of minutes because the pieces are so thin. While the chicken is grilling, place the rolls into a 350 degree oven until they are warmed and crispy on the outside.
 

To assemble, take your ciabatta roll and slice in half. Spread some mayo on the bottom half followed by lettuce, red onion, chicken and tomato. Spread some stone ground mustard on the top half of the bun and top the sandwich. Serve with a simple salad.
