Found this food truck at the Street Eats Festival at the Salt River Fields and out of all the options I tried I like Press the best. Other trucks didn't have a reduced price offering after visitors paid $12 to get in but Press delivered in this category with appetizers priced in the $1-$3 range and half sandwich/salad combos for $6.
The arugula side salad was quite plain dressed with just a tad of balsamic vinegar but they went nicely inside the Italian panini which came with salami, pepperoni, mortadella, and provolone. The website says that the Italian comes with a red pepper pesto but my sandwich appeared to come without this spread. Nonetheless it toasted, simple, and well executed.
At $6 one of the few places that delivered good food and value at the festival.
