Available for a limited time, Smashburger's new spring menu leans on bold flavors like truffle, jalapeño, and avocado. In total, there are four new smashburgers to choose from: the Avocado Bacon Ranch Stack Smash, the Green Goddess Bacon Stack Smash, the Jalapeno Crema Smash, Egg Truffle Mushroom Smash. Each one features a Certified Angus Beef patty, cheese, and flavorful toppings on a butter-toasted bun. In addition to the new burgers, there's also the new Mexicali Big Dog featuring chopped bacon and grilled jalapeños, as well as the new Avocado Arugula Green Goddess Salad made with organic arugula and leaf lettuce.
