Butterfly the chicken breasts, then rub each one down with the olive oil. Sprinkle with salt, pepper, and garlic powder to your preferred taste.
Grill chicken on medium-high heat for 5-6 minutes per side (the chicken being butterflied speeds this process way up!), or until it reaches an internal temperature of 165 degrees F.
While the chicken rests, assemble your salad: Divide each of the following between four large plates: bagged salad, chopped tomatoes, black beans, and corn.
Slice each of the chicken breasts into bite size chunks, and add on top of your salad.
Add the avocado, crushed tortilla chips, cheese, bbq sauce, and ranch dressing.
Enjoy!
