Heat the oven to 375°. Fold an 8-inch spinach wrap in half and use kitchen shears to cut a stegosaurus shape for easier cutting, trace it with a black food writer). Unfold and lightly coat one side of the wrap with cooking spray. Refold it (oiled side out) and lay it on a baking sheet. Place crumpled pieces of aluminum foil inside the wrap to hold the shell open as it bakes. Bake until slightly crisp, 2 to 3 minutes per side (the wrap will harden as it cools). Once it cools, draw a face with a food writer. Add green olive feet as shown and serve with taco fillings.
