A 10th-generation Romani-Serbian and current resident of Novato, Mark Adams runs a food truck with his wife, Deanna, that includes Serbian, American and Mexican flavors. He has a family recipe called chile mole salsa that goes back generations: Tomatoes, peppers and jalapeños are slow-roasted, then blended with seasonings and oil for an addictive sauce that is layered on everything from a street dog to vegan tacos and a club melt on sourdough. “Most people say it’s like nothing they’ve ever tried,” Adams says, who admits he will turn anything into a taco. Look for the truck on Saturday and Sunday at Larkspur’s Marin Country Mart and at the seasonal markets in Novato on Tuesday nights and Wednesdays in Fairfax.
