Subway offers alot of good choices (turkey,chicken and roastbeef subs) and they even have wheat bread (which i prefer) for everyone watching their intake of high g.i. carbs.
Even arbys has those deli sandwiches now, which i havent had a chance to try, but im sure are similiar in macro breakdown to subway. Also, a plain arbys roastbeef if i remember corectly isnt all that bad in the way of fat. Its when your tempted to go for the big montana that the fat,carbs add up.
