Meatlovers! If cooking protein, place in a large non-stick pan over medium-high heat with 2 tsp. olive oil. If using ground beef, break up until no pink remains and beef reaches a minimum internal temperature of 160 degrees, 4-6 minutes. If using diced chicken, pat chicken dry, and season both sides with a pinch of salt and pepper. Stir occasionally until chicken reaches a minimum internal temperature, 5-7 minutes. Add protein to filling with peas.
