Being in NJ, one of the usual spots to get dinner after youth group is a local diner
(there are a few we frequent). While, at times, I may indulge and get a grilled cheese sandwich, I figure a turkey sandwich (turkey, lettuce, onion, mustard) with a side of fruit is a better option.
I'm just not sure what bread is safest. I know most diners have wheat, white, and rye breads, maybe sourdough... and there's a good chance it's NOT 100% whole wheat bread, but brown colored white bread instead.
