Marinate the chicken in chipotle sauce, olive oil, salt, and pepper for at least 30 minutes.
Cook the rice according to package directions, then stir in chopped cilantro and lime juice. Set aside.
Sauté the sliced bell peppers and onions in a skillet over medium-high heat until softened and slightly charred.
Grill or pan-sear the marinated chicken for 6-8 minutes per side until fully cooked, then chop into bite-sized pieces.
Warm the black beans in a small saucepan over low heat.
Assemble the bowls by layering the seasoned rice, beans, chicken, and fajita vegetables.
Top with lettuce, cheese, pico de gallo, corn salsa, guacamole, and sour cream before serving.
