Place chicken tenders, olive oil and chipotle chili powder in the slow cooker. Cook on low for 4 hours.
When the chicken is done (check to ensure that it is fully cooked), lay out the flat wraps and drizzle 1 tablespoon of Hidden Valley® Greek Yogurt Ranch over each one.
Top wraps evenly with tomatoes, corn, black beans, avocado and chicken. Serve immediately.
