Has the food-truck phenomenon already crashed and burned in Las Vegas due to overhype? No, and a big part of the credit goes to Jolene Mannina, who launched her truck Dec. 30 and has lived up to the hype each day since. There is no set menu in her Sloppi Jo’s Roving Eatery, but she always has sliders, pork tacos, breakfast burritos and the Sloppi Jo (red chili pork topped with a fried egg). If she has a batch made, don’t miss the Hatch green chili mac and cheese. Find her latest location by visiting SloppiJos.com.
