Preheat your oven to 350° and remove all plastic from the tray. Place the aluminum tray onto an oven-safe baking sheet. Bake for 45 minutes or until hot. If baking from frozen, add 30 minutes. Once hot, remove from the oven and allow to sit for 5 minutes before serving. For an extra wow, add sour cream or chopped cilantro from your fridge!
