Spicy sweet potato chip and avocado sammie

January 1 often marks the day that people start new diets, resolve to lose weight or exercise more, etc. But this year I'm trying to take the pressure off all of those green salads and smoothies, and offer a not-bad-for-you baked sweet potato chip sandwich. There was a lunch spot near us that offered a sweet PLAT sandwich (sweet potato, lettuce, avocado and tomato) that was kind of insane and ever since it closed, I knew making some variation of it was in my near future. And ever since making Ashley Rodriguez’s special sauce from her book Date Night In, I knew that needed to make an appearance in this sandwich as well. So, if you're a fan of sweet potato fries, sandwiches, spicy sauce, avo and some greens for good measure, then I have you covered! I like cutting the sweet potato quite thin, as I prefer a crunchier sandwich. However, if you prefer a softer chip, slice the potatoes to 6 mm thickness; you may have to adjust the cooking time as well.
