Prepare Tyson chicken according to package directions. Place a slice of cheese and 2 slices of bacon on top of each chicken breast; heat for an additional 4-5 minutes until cheese melts. Set aside and keep warm.
While chicken is cooking place tomatoes in a shallow bowl. In a mixing bowl, or by using a whisk, mix together olive oil, balsamic vinegar, Dijon mustard, salt and pepper. Pour over tomatoes; let marinate for 10 minutes.
Finely chop 8 of the basil leaves. In a small bowl combine the mayonnaise and chopped basil. Spread the basil mayonnaise over the cut sides of warm, toasted focaccia rolls. Layer the bottom with the prepared Tyson Chicken Breast, 2 marinated tomatoes and 2 fresh basil leaves. Close sandwich with remaining toasted roll. Enjoy!
