Add chicken to pan, turning regularly and swirling in pan for about 10-15 minutes, until chicken is cooked through.
Meanwhile, heat a stainless steel skillet over medium-high heat with 1 TBS of Olio Taibi Biancolilla Extra Virgin Olive Oil (only until oil is shimmering, do not allow oil to smoke), add peppers, a pinch of salt and freshly ground pepper, and sauté until peppers are soft and tender, and 10-15 minutes.
Transfer chicken to a board and slice thinly.
Spread pesto onto both sides of all 4 of the sliced ciabatta rolls, divide evenly and pile in chicken, top with peppers, drizzle a little more Olio Taibi Biancolilla Extra Virgin Olive Oil onto each sandwich, and enjoy!
Make 2 foil packets for the peppers (divide evenly):
1. Using two rectangular sheets atop one another of heavy duty foil for each packet, make a foil pack for the peppers.
2. Season peppers with salt and fresh ground black pepper.
3. Drizzle each pack with 1/2 TBS Olio Taibi Biancolilla Extra Virgin Olive Oil
4. Close packs, crimping foil together.
Get your grill or fire pit at a medium heat level, place foil packets either directly on coals or on grates. Let cook for about 15-20 minutes. Check halfway through to be sure the aren't burning. if cooking too fast, open top of packets a little to let off steam, and place on grates.
Place chicken on grates and cook for about 15 minutes, turning occasionally until chicken is cooked through.
