In a small bowl mix together taco seasoning, oil and lime juice. Rub on all sides of chicken breasts then place into a large plastic storage bag, seal and chill for at least 4 hours or overnight.
Chicken: Brush the grates of a gas grill with oil. Preheat to medium-high. Grill the chicken breasts for 4 minutes per side or until the juices run clear and the chicken reaches an internal temperature of 165°F.
Remove to a platter to allow the chicken to rest for 5 minutes before slicing
Roasted Corn: Preheat the oven to 450°F. Move oven rack to upper third of oven. Use a non stick baking sheet or line with foil, spritzed with cooking spray.
Spread corn on pan with jalapeno and red bell pepper. Spritz lightly with cooking spray. Season with garlic salt and black pepper, toss to combine. Spread in a single layer. (Eyeball amount of seasonings to your taste)
Roast for 15-18 minutes, until the corn begins to caramelize. Remove from the oven to cool slightly.
Assemble: Toss the salad greens with the red pepper slices, tortilla strips, roasted corn, black beans and arrange the sliced chicken on top.
