  • 3 pounds boneless skinless chicken breasts
  • Marinate:
  • 1/4 cup prepared stone ground mustard
  • 1/4 cup olive oil
  • 1/2 cup balsamic vinegar
  • 2 tablespoons packed brown sugar
  • 2 tablespoons onion powder
  • 2 teaspoons garlic powder
  • salt and pepper to taste


  1. Place the chicken pieces, one at a time in between two layers of wax paper or in a large Ziploc bag. Using a rolling pin or meat tenderizer pound chicken to about 1/2-inch thickness. Using a sharp knife, cut the chicken breasts in half.
  2. In a clean Ziploc bag add the ingredients for the marinate. Squish together good with your fingers. Place flattened chicken pieces in the bag and refrigerate for a minimum of 2-3 hours.
  3. Grill in a hot pan over medium heat, in 2 tablespoons of canola oil and 1 tablespoon of butter, for about 2-3 minutes per side or until no longer pink inside. Use tongs to flip over.
  4. Let rest briefly before assembling on rolls. Spread a thin layer of mayonnaise on one side of a kaiser roll.
  5. Top chicken with slices of fresh tomatoes, lettuce, avocado and Cabot cheddar cheese.
