Start with plates (end with utensils) followed by tortillas and/or taco shells. Set the rest of your taco components out—in separate chafing dishes, ramekins or bowls—in the order you would build your taco:
Proteins
Beans
Rice (or other grains)
Veggies
Salsas
Cheeses
Lettuce and slaws
Guacamole, cremas, sour cream
Finishing touches—jalapenos, onions, cilantro, sriracha or your favorite hot sauces.
