Pesto-Mozzarella Stuffed Chicken Breasts
4 boneless skinless chicken breasts -- rinsed and patted dry
freshly ground black pepper
1/2 cup Pesto Sauce
1/2 cup mozzarella cheese -- perlini fresh mozzarella balls (or use larger balls cut into small pieces)
1/2 cup Roasted Red Peppers
Prepare a charcoal or gas grill for direct, high heat.
While grill heats, with a sharp knife, cut a pocket lengthwise in the edge of each chicken breast half, taking care to avoid cutting through to the other side. Season chicken pieces on both sides with pepper.
Spread about 1 tablespoon pesto inside each pocket, then fill each with 1/4 of the mozzarella balls and 1/4 of the roasted red pepper slices. Rub remaining pesto over exterior of chicken to coat lightly.
Place chicken on oiled cooking grate; cover gas grill. Cook, turning once with a wide spatula, until meat is browned and no longer pink in center (cut to test, but do not disturb filling), about 15 minutes total.
