Puebla vendors usually serve an order half with red salsa and half with green, so a single plate shows off both sauces.
Small, thin corn tortillas are fried in lard on a wide griddle, then topped with red or green salsa, shredded pork or chicken, and chopped onion, and served several at a time on a small plate. Puebla's street carts and market counters sell them as a quick afternoon bite.
