Potato Okonomiyaki – What to do with left over vegetables from your holiday feast? Pancake them for breakfast the ing day! I incorporated the mashed potatoes that came with thetreedots duck confit into my batter and reduced the amount of liquid used. The end product was like a crossover between Korean Potato pancake and Okonomiyaki! Kept this vegetarian by using sliced cabbage only but I bet pre-cooked bacon would be great as an add in. Also, used the gravy that came with the duck as the okonomiyaki sauce, adding a touch of ketchup to sweeten it.
