CUESA (The Center for Urban Education about Sustainable Agriculture) is hosting their SECOND ANNUAL GRILL FEST: BURGER CHALLENGE. Four local chefs will be battling it out on the grills: Mark Sullivan of Spruce; Andrew Swallow of Mixt Greens; Taylor Boetticher of Fatted Calf; and Elizabeth Falkner of Orson. Chefs will be provided with all-natural grass-fed beef from Marin Sun Farms, and each will be creating a surprise side dish with ingredients they will individually source from the farmers' market the day of the event.

Want to be a judge? There's one lucky guest spot that will be drawn by either signing up at the CUESA kitchen, or by email to sarah@cuesa.org. A limited amount of mini-burgers will be available for audience members to enjoy for a $2 donation, all proceeds going to CUESA. Saturday June 27th, 11am-12:30pm.
