Zucchini & Sweet Potato Slice is one of the earliest recipes that I shared on Becomingess. I decided to change it up a bit and make it without the feta as I (and most of you by the looks of it) prefer dairy free recipes. So it is now listed as an optional ingredient. I have also included 1/2 teaspoon chili flakes as an optional ingredient, as I found that it makes a nice addition to the slice. But it is totally up to you if you would like to include it or not.
