In large bowl, mix flour, baking powder, sugar, baking soda and 1 teaspoon salt. Cut in butter, using pastry blender (or pulling 2 table knives through ingredients in opposite directions), until mixture looks like coarse crumbs. Stir in cheese and green onions. Add buttermilk; stir just until combined. Drop dough by rounded tablespoonfuls evenly onto sausage mixture.
