For many, Subway is the perfect stop for a quick, “cheap” and healthier lunch option — even more so with its latest daily special. For $6, get a Footlong “Sub of the Day.” Here’s the weekly line-up: Sunday – Meatball Marinara; Monday – Sweet Onion Chicken Teriyaki; Tuesday – Oven-Roasted Chicken; Wednesday – Turkey Breast; Thursday – Italian BMT; Friday – Tuna; and Saturday – Black Forest Ham. There is an additional charge for extras, including double meat. The deal is for a limited time at participating locations. (If you’re not quite as hungry for a Footlong, many locations continue to offer the same daily promo for a 6-inch at $3.50.)
