Preheat oven to 375 degrees F. Lightly spray a 12-cup muffin tin with cooking spray.

Saut, onions in butter or oil until soft. Let cool. Transfer to a large bowl and add egg. Stir in buttermilk, cheese and seasonings.

Sift together whole-wheat flour, salt, baking powder, and baking soda. Combine with oat flour. Add cheese mixture, stirring just enough to mix.

Spoon into muffin tin and bake about 15 minutes. When done, muffins will be a pale, creamy color on top and golden brown on sides and bottom.

Helpful Hints: To make oat flour, blend 1/2 to 3/4 cups of rolled oats at a time in a blender or food processor.
