Meatlovers! 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 chicken breasts, on a separate cutting board, pat dry and cut into 1” dice. Stir occasionally until chicken reaches minimum internal temperature, 5-7 minutes. If using Impossible burger, break up burger until heated through, 4-6 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 ground beef, break up beef until no pink remains and beef reaches minimum internal temperature, 4-6 minutes. Add to flautas as desired.
