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 Impossible burger, break up burger until heated through, 4-6 minutes. If using diced chicken, pat dry and stir occasionally until chicken reaches minimum internal temperature, 5-7 minutes. If using shrimp, pat dry and cook undisturbed until seared on one side, 2-3 minutes. Flip, and cook until shrimp reaches minimum internal temperature, 1-2 minutes. If using flank steak, 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. Add proteins to flatbread as desired.
