ingredients in a bowl; cut in margarine (with pastry blender) until like coarse meal. Add yogurt, stirring just until moistened. Plop onto a floured surface and knead 4-6 times. Make two balls, pat each until 1/2" thick (perhaps 6" across) and cut each circle into 6-8 wedges. Place each wedge evenly spaced on a cookie sheet which has been coated with non-stick spray. Bake 5-12 minutes, or until lightly brown.
