A recent visit to the White House farmers market (810 Vermont Ave. NW; Thursdays through Oct. 31, 11 a.m.-2:30 p.m.) yielded a very welcome discovery: Chaya tacos ($9 for three, chayadc.com).

Helmed by local chefs Bettina Stern and Suzanne Simon, Chaya is a restaurant concept with an emphasis on vegetarian Mexican cuisine. Stern and Simon are looking for a permanent home to open a brick-and-mortar restaurant.

For now, a weekly rotation of tacos will be available at the White House market and the District Flea, which opens this Saturday (945 Florida Ave. NW; Saturdays through Oct. 19, 10 a.m.-5 p.m.). Varieties include kale and roasted potatoes with creamy poblano sauce; smoky zucchini with bovre cheese and radish; and roasted winter squash with chili, queso and mint.

The tacos, served on handmade corn tortillas that take up to five hours to make, are topped with a delicate bouquet of microgreens and tangy chipotle yogurt sauce. “It’s totally different than something you can get out of a package,” Stern says of the handmade tortillas. “It makes all the difference.”
