Meat lovers! If using steak strips or flank steak, separate into a single layer and pat dry. Season with a pinch of salt and a pinch of pepper. Place a large non-stick pan over medium-high heat and add 1 tsp. olive oil and steak to pan. Stir occasionally until no pink remains and steak strips reach a minimum internal temperature of 145 degrees, 4-6 minutes. If using shrimp, season with a pinch of salt and pepper and heat 1 tsp. olive oil in a large non-stick pan over medium-high heat. Cook undisturbed until seared on one side, 2-3 minutes. Flip, and cook until shrimp reaches minimum internal temperature, 1-2 minutes. Add to tacos as desired.
