Meat lovers! If adding protein, cook in large non-stick pan, then transfer to a plate before cooking vegetables in Step 2. Top flautas with filling, or serve on the side. If using chicken, pat dry. Season all over with ¼ tsp. salt and a pinch of pepper. Stir occasionally with 2 tsp. olive oil over medium-high heat until chicken reaches minimum internal temperature, 5-7 minutes. If using shrimp, pat dry and season with a pinch of salt and pepper. Cook with 2 tsp. olive oil over medium-high heat until shrimp reach minimum internal temperature, 2-3 minutes per side. If using ground pork, combine with 1/4 tsp. salt and a pinch of pepper. Cook with 1 tsp. olive oil over medium-high heat. Break into small pieces with a spoon until no pink remains, 5-7 minutes.
