Another great bargain lunch can be found at Subway. Look closely at the menu, usually on the far right, near the sides and drinks and you will find the Mini Sub, which has just replaced the former Deli Sandwich.
The mini sub is similar to the classic subs, but served on a 4-inch roll, instead of a 6-inch roll. You have a choice of several different breads, as well as tuna, ham, roast beef or turkey. You can load your mini sub with all of the standard toppings as well. Best of all, this sandwich is $2.49 everyday. Take your change to the vendor on the street corner and add a bag of pretzels or Sun Chips for just $0.50 (they cost $0.89 inside at Subway) and you've got a $3 lunch! (That picture is of the tuna mini sub I ate for lunch today.)
