Preheat your grill or stovetop grill pan over medium-high heat.
Season the chicken breasts with cumin, chili powder, garlic powder, paprika, salt, and pepper. Make sure both sides are evenly coated.
Grill the chicken for about 6-8 minutes per side, or until cooked through. The internal temperature should reach 165°F (74°C). Set aside and let it rest for a few minutes before slicing into thin strips.
In a large salad bowl, combine the black beans, corn, diced red bell pepper, avocado slices, and diced tomato.
In a small bowl, whisk together the lime juice, olive oil, honey or maple syrup, chopped cilantro, minced garlic, salt, and pepper to make the lime cilantro dressing.
Add the sliced chicken to the salad bowl and drizzle the lime cilantro dressing over the ingredients.
Gently toss everything together until all the ingredients are well coated with the dressing.
Serve the Southwest chicken salad on a bed of lettuce.
