If you include veggie subs at subway, then 3+ times a week or more lol. I love subway, although with the crackdown on veggie free double cheese I'm not really hitting em up that much anymore (now most subways don't give you anything extra in a veggie over say another $5 footlong such as turkey, but you can't get meat so you basically pay for a ham sub without the meat which takes the appeal out of subway for me).
Not including subs, probably once a week.
