OP, those were the exact 2 I was going to put there. Subway has mediocre, at best, sandwiches, but their white chocolate macadamia nut cookies are damn good.
The Walmart brand of the gluten free chocolate chip cookies are mighty damn good compared to even regular cookies. I sometimes spice it up a bit and add some chips of different flavors to the mix like white chocolate, butter scotch, or peanut butter.
