McDonald’s has temporarily brought back what the ubiquitous fast-food chain describes as “everyone’s favorite sandwich.” The Smoky BLT Quarter Pounder with cheese began its limited run on July 10, Fox Business reported. The sandwich will only be sold “while supplies last” — so time’s already running out. The sandwich consists of a “100% fresh beef quarter pound patty, two slices of melty American cheese, thick cut applewood smoked bacon, juicy Roma tomatoes, shredded lettuce, smoky sauce and a toasted sesame seed bun.” Smoky BLT Quarter Pounder Returns to McDonald’s – https://t.co/zCzQZqC7Eu …
