A is for Add-Ons: According to the 2012 Avocado Menu Trak study, avocado was mentioned on 32.9 percent of menus in 2012, an increase of 11.5 percent over 2009. The most common uses for avocados are on sandwiches. A fresh idea from La Condesa Napa Valley in St. Helena, CA is executive chef Chris Mortenson’s Avocado Torta with black bean puree, heirloom tomato, queso fresco and chipotle mayonnaise.

B is for Burger Enhance-ment: According to Technomic’s 2011 Burger Consumer Trend Report, more than one-third of consumers will pay more than $6 for a premium burger. Signature recipes, burger of the week promotions and other specialties create buzz. At the recent 2013 World Burger Championship in Las Vegas, head cook Wade Fortin accepted the $10,000 prize for Second City Smoke’s winning El Toro—a porcini butter-stuffed rib-eye steak cheeseburger.

C is for Condiments: Signature touches go way beyond slices of onion on sandwiches. Consider adding a dollop of onion marmalade to veggie burgers, topping grilled tuna with pickled ginger onion relish, piling sweet onion jam on grilled cheese sandwiches, and garnishing chicken sandwiches with crispy fried onion straws and barbecue sauce.
