Meatlovers! Cook proteins in a medium non-stick pan over medium heat. Add to penne as desired. If using bacon, line a plate with a paper towel. Add to pan and flip occasionally until crisp and bacon reaches a minimum internal temperature of 145 degrees, 6-8 minutes. Transfer to towel-lined plate. If using jumbo shrimp, pat dry and season all over with a pinch of salt and pepper. Cook undisturbed until opaque and shrimp reaches minimum internal temperature, 2-3 minutes per side. If using diced chicken, pat dry and season with a pinch of salt and pepper. Stir occasionally until chicken browns and reaches minimum internal temperature, 5-7 minutes.
