Meat lovers! Cook proteins in a large non-stick pan over medium-high heat with 1 tsp. olive oil. If using flank steak, separate, pat dry, and season all over with a pinch of salt and pepper. Stir occasionally until no pink remains and steak strips reach a minimum internal temperature of 145 degrees, 4-6 minutes. If using shrimp, pat dry. Cook until shrimp reaches a minimum internal temperature of 145 degrees, 2-3 minutes per side. If using ground beef, break up meat until no pink remains, and reaches a minimum internal temperature of 160 degrees, 4-6 minutes. Add to pasta as desired.
