"I've used all sorts of different oil making this bread: olive, avocado, melted coconut. You could also use canola or vegetable oil. The vital wheat gluten is optional but I highly recommend it if you want a really soft, light, chewy loaf of bread. Another alternative is to use bread flour in place of the white flour (and omit the gluten). Also, if you don't have wheat flour, you can make this with 100% white flour. I haven't tried making this with all whole wheat flour - if you experiment, I'd suggest increasing the kneading time by a few minutes to really develop that gluten and get a soft, light loaf.The oats in the recipe are more for looks - and they tend to fall off while slicing but I like the look and texture of them so I've kept them along for the ride. You could easily omit them if they're not really you're thing.This recipe transitions very well to rolls (about 12-14) or any size of loaves...."
