Meatlovers! Cook proteins in a medium non-stick pan over medium heat. If using diced chicken, pat dry and season all over with a pinch of salt and pepper. Stir occasionally with 1 tsp. olive oil until chicken reaches minimum internal temperature, 5-7 minutes. If using steak strips, separate into a single layer and pat dry. Stir occasionally with 1 tsp. olive oil until no pink remains and steak reaches a minimum internal temperature of 145 degrees, 4-6 minutes. Add to penne as desired.
