Meat lovers! If adding protein, season with a pinch of salt and pepper and cook with 1 tsp. olive oil in a large non-stick pan over medium-high heat. If using diced chicken, pat dry and stir occasionally until chicken reaches minimum internal temperature, 5-7 minutes. If using steak strips, separate into a single layer and pat dry. Stir occasionally until no pink remains and steak reaches minimum internal temperature, 4-6 minutes. Rest, 3 minutes. If using Impossible burger, break up burger until heated through, 4-6 minutes. Add to sandwich as desired.
