Meat lovers! Season all meats with a pinch of salt and pepper. If using diced chicken, pat dry. Stir chicken occasionally in a medium non-stick pan over medium-high heat, with 2 tsp. olive oil, until chicken reaches a minimum internal temperature of 165 degrees, 5-7 minutes. If using shrimp, pat dry. Use same pan, heat, and oil as chicken. Cook shrimp on one side, 2-3 minutes, then flip and cook until they reach a minimum internal temperature of 145 degrees, 1-2 minutes. If using ground beef, use same pan and heat as chicken and shrimp. Cook, breaking up meat with a spoon, until no pink remains, 4-6 minutes. Top cooked pizzas with meat before adding zucchini ribbons.
