barefoot.. Here's a recipe that was listed with the bun recipe

Make your own Atkins Bake Mix

1 cup soy flour
2 cups soy protein isolate
2 tablespoon baking soda
1 teaspoon salt
2 tablespoons Splenda

Sift together then store and use as you would Dr. A's. It's much cheaper and things come out about the same.
