Prepare your working space with- a large cutting board, a pizza slicer or large knife, a small bowl filled with water, and a pastry brush for brushing tortillas with water.
Heat oven to 500° F
Mix sugar and cinnamon in a shallow bowl or a large plate.
Working with one tortilla at a time, slice each tortilla into triangles. (Any size is fine, I usually get 18-20 triangles per large tortilla).
Brush each triangle on one side, lightly, with water. Dip (water side down) into cinnamon-sugar mixture. Shake off excess.
Place tortilla triangles, cinnamon-sugar side up, in a single layer on a tin-foil lined cookie sheet sprayed lightly with non-stick spray.
Bake in 500° F oven for 4 to 5 minutes, or until just browned around the edges. Remove baked tortillas to a large bowl lined with paper towels, to cool.
Repeat for next batch. This will produce about 4 to 5 cookie sheets worth.
Once cooled, the chips can be stored in a large zip-lock bag or plastic container with lid.
