Preheat 1 Tablespoon oil in a large pan to high, add chicken to the pan in a single layer. Let it cook undisturbed for 3 or 4 minutes on one side.
Then add salt and onion powder, redistribute chicken, ensuring that the uncooked side of each piece is touching the cooking surface, then cook another 4 or 5 minutes until all chicken is opaque and cooked through.
