Open all the cans of biscuits and each biscuit into quarters. Fill a large Ziploc bag with the white sugar, the orange zest, and the dash of salt. Seal the bag and shake it until the zest and the sugar are totally combined. Add the biscuit pieces to the bag, seal it and shake it around until all the biscuit pieces are coated in the orange sugar. Don't give up, keep shaking until each piece is nicely coated. Pour the pieces into a bundt pan and set it aside.
