In celebration of its biggest menu change in 60 years, Subway is giving away one million free sandwiches on Tuesday. To get a complimentary sub, customers need to visit a restaurant between 10 a.m. and 12p.m. Subway introduced 12 new signature sandwiches last week. There are four different categories on the Subway Series menu. There are three types of cheesesteaks: The Philly, The Outlaw and The Monster. Supreme Meats and The Boss are Italianos. Chickens include The MexiCali, The Great Garlic, and The Champ. The All-American Club, Subway Club, and Turkey Cali Club are all clubs. The Subway Series is the most ambitious undertaking in company history, as we are changing the nearly 60-year-old blueprints that helped make Subway a global phenomenon. The Subway Series enhances the entire Subway guest experience after last summer's Eat Fresh refresh. A new menu and ordering system made it easier for guests to order. Guests can simply say a sandwich number or name if they want, instead of having to pick their ingredients. You can find full sandwich ingredients at Subway.
