Sounds good! For this one, I used Daiya provolone slices, which are pretty decent. My favorite is the Chao slices, but those are a little more expensive.
I love seitan! It's basically 100% gluten, so gluten-free people can't do it, and that's definitely been a trend in vegan food over the past handful of years. I am still kind of an old-school vegan. ha.
I thought for a while that I was gluten intolerant, so I went gluten free for about 6 months to see how my body would react if I slowly introduced it again.
I haven't had any symptoms and I have been eating a lot of wholegrain bread and pasta, so the seitan shouldn't be any different.
It's always worth a shot. I certainly don't eat it every day or anything.
