Cut the chicken breast into 1-2″ chunks. Put them in a container with 1 tbsp olive oil and 2 tbsp ranch seasoning. Stir to coat with seasoning. Let rest in the refrigerator for 10-15 minutes.
Heat remaining oil in a skillet over high heat. Add the chicken and spread into a single flat layer. Let cook 4-5 minutes without stirring or moving the chicken.
Then flip the pieces over and cook an additional 3-5 minutes or until the chicken is cooked through (165˚F internal temp).
Serve hot with your favorite sides. Enjoy!
