1. Preheat oven to 425°.
2. Combine first 4 ingredients in a medium bowl; cut in margarine with a pastry blender until mixture is crumbly. Combine yogurt and honey; add to flour mixture, stirring with a fork just until dry ingredients are moistened.
3. Sprinkle 1 tablespoon flour over work surface. Turn dough out onto floured surface; knead lightly 4 or 5 times. Roll dough to 1/2-inch thickness; cut into rounds with a 2-inch biscuit cutter. Place biscuits on an ungreased baking sheet. Bake at 425° for 10 minutes or until golden.
