In a skillet over medium heat, add olive oil. Once hot, add the shredded chicken, chili powder, cumin, garlic powder, salt, and pepper. Stir to combine and cook for about 5 minutes until heated through.
While the chicken is heating, prepare the salad base by placing the chopped romaine lettuce in a large bowl.
Top the lettuce with cherry tomatoes, black beans, corn, diced avocado, and shredded cheddar cheese.
Once the chicken is ready, add it on top of the salad.
Drizzle salsa and sour cream over the salad bowls.
Serve with tortilla chips on the side for crunch.
