1Heat oven to 400º. Spray 2 cookie sheets with cooking spray. Mix flour, cheese, onions, cilantro, baking powder, baking soda, salt and red pepper in large bowl. Cut in butter, using pastry blender or crisscrossing 2 knives, until mixture looks like fine crumbs. Mix apple juice, 1/3 cup yogurt and the egg; stir into flour mixture until dough leaves side of bowl.
2Turn dough onto lightly floured surface. Knead about 1 minute or until smooth. Divide dough in half. Roll each half into 9-inch circle that is 1/4 inch thick. Place each circle on cookie sheet. Cut each circle into 12 wedges with floured knife, but do not separate. Brush 1 tablespoon yogurt over each circle.
3Bake 15 to 17 minutes or until golden brown. Carefully separate wedges; remove from cookie sheets to wire rack. Serve warm.
