Grate the veggies using the largest holes on a box grater. Mix them together in a bowl with the oils, salt and pepper. If using scallions and/or hot sauce add them to the mixture.                                                                                                                            Remove the hard stem/rib of the greens but keep the leaves intact. Rinse the leaves and blanch (in simmering water) for a few seconds. Lay out on a platter.      Place the veggies in the middle of each leaf, sprinkle them with walnuts and cubed avocado. Close the leaf like a burrito or a wrap, and enjoy.  (Recipe♦698)
