This recipe was given to me by a friend and I made one change to the type of fat used. It takes some prep time so I like to combine the dry ingredients the night before or make several batches of dry ingredients and store in quart zip type bags in the pantry. It's good to label these and attach a copy of the recipe. I most recently tried mixing the wet ingredients, except the egg whites and melted butter, the night before and refrigerated it until morning. This also worked well and really cut down on the morning prep time. Just add the melted butter to the pumpkin mixture. Beat the egg whites and combine as stated. Freeze any leftover waffles and put them in the toaster for a quick breakfast.
