This recipe does have a kick to it, but you could tone it down to make it more kid friendly. I suggest omitting the chipotle in adobo in the walnut meat cauliflower taco mixture, and then omitting the jalapeno in the pickled beets. If you want to serve this to young toddlers, just make extra sure there is no large pieces of walnuts left in the mixture and that everything is minced very fine.
