Eggs are a great protein source, and more limited-service chains and airport kiosks are offering simple hard-cooked eggs as snacks. Now, though, deviled eggs are trending at full-service restaurants, with operators adding signature touches to this Southern classic. Fatz menus deviled eggs spiked with hot sauce and topped with crispy pork skin, paprika and herbs. Soon-to-open The Capital Burger, Darden’s spinoff of The Capital Grille, also menus deviled eggs on its snack menu. Its version is topped with candied smoked bacon.
