How to Make It
Preheat oven to 350°. Stir together baking mix, baking powder, and salt in a large bowl. Stir in milk and remaining ingredients, stirring just until dry ingredients are moistened. Spoon cheese mixture into a lightly greased 15- x 10-inch jelly-roll pan.
Bake at 350° for 30 minutes or until golden brown and set. Remove from oven, and let cool on a wire rack 10 minutes. Cut into 1 1/2-inch squares, and serve immediately.
