Preheat oven to 425° F. Mix together flour, baking powder, and salt in a large bowl. Cut in the chilled margarine and cut it roughly into the flour using a pastry cutter, or with a few pulses of your food processor until mixture is the texture of coarse meal. A few remaining lumps are ok. Take care not to overwork the dough, or let the margarine melt.
Add your Cashewmilk Yogurt and stir with a wooden spoon until just combined. Again, do not overwork or your biscuits will be tough.Transfer the dough to a lightly floured surface and pat into an oblong shape, about 1 1/2 inches thick.
Using a 3 inch floured biscuit cutter (or a glass from your cabinet), cut the biscuits out and place them on a parchment-lined baking sheet (easy clean-up!). Brush the tops lightly with melted margarine and bake for about 12 to 15 minutes, or until they begin to turn golden. Remove biscuits from oven immediately and transfer to a wire rack to cool.
