This is my version of healthier (no saturated fat frying) onion rings.
I use Oat Bran as many of you know, for baking pancakes, cookies, etc. It has fiber and helps lower cholesteral, and keeps a feeling of fullness and satisfaction.
Just substitute your usual bread or flour oat bran with seasoning you like as dry batter with egg beaters and yogurt as the wet dipping batter, and bake at 400 for 20 or so, flipping halfway through. Delish.
