I decided to use a coupon I got in the mail (randomly....not requested) for a free sub from Erberts and Gerberts. It worked perfectly for lunch today....Sweet Chili Chicken Salad on Wheat. It was a lot of food too, I've actually got two lunches out of it now! Basically, it was a sweet-chilli mayonaise based chicken salad, layerd with chopped lettuce, red onions sliced, and some bacon slices. I think I can make that at home. :)
Other free food coming up that I'd like to try is the free KFC meal (coupon print valid today, coupon is good till the 19th), and also the free iced tea at Arbys. These were mentioned on Hip2Save's site.
