Have you ever had a Mexican haystack? Layers of chips, covered in beans, rice, meat, cheese, more cheese, sour cream, guacamole, make a few tomatoes thrown in for good measure? They are very yummy, although very high in calories.
I set out to make some with some great flavors in mind. I started by peeling, cubing, and roasting a couple of sweet potatoes.
These took the place of my chips.
