"A standout truck among the stellar lineup of Latin American cuisine at the Portland Mercado, Tierra del Sol serves up authentic Oaxacan dishes, including tlayuda: a 14-inch crispy corn tortilla topped with asiento (chicarrón bits), black beans, queso Oaxaca and queso fresco, cabbage, tomatoes, red onion, radish, avocado, and cilantro. (It’s enough to feed two.) The cart also features a variety of moles, which all have richly complex flavors. Try the Mole Coloradito, the traditional red mole of Oaxaca, or the Pipian de Pollo, a green mole that originates from owner Amalia Sierra’s hometown. Patio seating is available, Tierra del Sol’s website takes orders online." - Janey Wong
