Add ingredients for the chipotle ranch dressing to a small blender and blend until completely smooth. Refrigerate until ready to use.
Heat the oil over medium heat in a skillet and add the chopped chicken. Sprinkle with chili powder and sea salt. Cook, stirring occasionally, until chicken has cooked through, about 5 to 8 minutes. Remove from heat and set aside.
Divide greens among two to three salad bowls, and arrange remaining salad ingredients on top (including cooked chicken). Drizzle with desired amount of chipotle ranch dressing and serve.
