In large bowl, stir yogurt and hot sauce until smooth. In another bowl mix flour, paprika, pepper and salt. Add chicken wings to yogurt mixture; toss to coat; then dip wings into flour mixture to coat. Let wings sit for about an hour so the coating sticks. Preheat oven to 425 degrees. Arrange wings in single layer in large roasting pan. Drizzle with melted margarine. Bake wings for 35 minutes or until fork tender.
