Some readers may recall that in this space two weeks ago, I lamented the disappearance of the Rasta vegan-food truck that had been parked at 24th and K streets. No sooner had that article appeared than I received a tip from an alert reader: The truck is back! I hastened to the corner, and what to my wondering eyes did appear but Roots-N-Kulchah Vegan Food, a bright-yellow truck parked in a formerly vacant lot. There’s a big printed menu, but what’s actually available varies. The friendly workers are willing, even eager, to dispense samples, so I tried a sweet and delicious vegan “shrimp” in a spicy sauce as well as the hot and smoky Rastaman tofu, a pastry-wrapped vegetable patty and a sweet-potato fritter. The curries come with a heap of brown rice, a side of greens and fried plantains. A laid-back atmosphere, complete with music, is an extra bonus. 24th and K streets, (916) 705-4770.
