Fans of pepitas and mole, this is your dish. Pipián verde is a sultry, savoury sauce based on toasted squash (pumpkin), sesame seeds and green chiles — and, when it's at its best, that's what it should taste like. La Casa de Pepe, a popular lunch spot for local professionals, serves a reasonably sized portion that doesn't disappoint. Order it with chicken or pork; it pairs well with both.
