Heat olive oil in a large sauté pan over medium-high. Season the chicken with salt and pepper and sear for 6 minutes on each side until cooked through and browned all over. Move to a cutting board and let sit for 5 minutes. Then dice the chicken.
In a food processor, combine the cilantro, lime juice, chipotle peppers and the adobo sauce. Process until smooth.
Add the chicken back to the pan, along with the chipotle sauce, freshly diced red bell pepper. Toss until combined.
Serve a couple of Tbs. of the chicken mixture in each lettuce cup and garnish with scallions!
Begin by Turn on the broiler. Arrange the corn on a rimmed baking sheet with a tsp of oil and a pinch of salt and pepper. Broil the corn for about 5 minutes, or until they start to slightly char and turn crispy. You can toss them a couple of times throughout. Set aside. (Again corn is only ok for Phase 4 dieters) Phase 1-3 dieters should just skip this step.
Phase 4 modifications:
1 cup frozen corn (Phase 4 only) All other dieters could just use more bell peppers instead of corn
