Notes
This Seitan Steak Sandwich is one of my most favorite ways to use my seasoned seitan steak! The seitan is a great recipe for meal prepping because you can throw a sandwich like this one together in only a few minutes on a week night and make everyone really happy!
This Seitan Steak Sandwich is inspired by Steak-Umm sandwiches I used to have as a kid growing up in the Midwest. I haven’t had one since I was 12 years old (that’s when I stopped eating meat), but biting into this seitan sandwich was very nostalgic to me. Being a vegan is easy to stick to if you’re committed to your beliefs, but it’s much easier to stick to when you have tasty recipes that remind you of home. If you have any childhood recipes you’d like me to take a crack at vegan-izing or high protein-izing, send me an email or dm! I’m all about making it as easy as possible for all of us to stick to our vegan diets for life! 🙂

Ingredients
- Seasoned Seitan Steak – I’m not going to go into all the details of how to make this here, because it will be redundant to the excruciatingly detailed recipe page I already have dedicated to it. High level – you need silken tofu, black beans, vital wheat gluten, nutritional yeast and some seasoning!
- Hoagie Bun/French Roll – I use store-bought. Make sure you get something decently large to fit in all of the goods.
- Baby Bella Mushrooms – any mild-flavored mushrooms will do just fine; these just happen to be my personal favorite!
- Vegan Mozzarella – I really like the Miyokos brand mozzarella that comes in a brick because you can slice off whatever size you need. Any vegan mozzarella will work great though!

Instructions
- Make the seasoned seitan steak per the recipe link above.
- Thinly slice the seitan similar to the picture above.
- Clean and thinly slice the mushrooms.
- In a medium heat pan, sautee the mushrooms. This should take around 10 minutes. I like to get most of the excess water out and carmerlize them a bit for that deep brown color.

- Add the thinly slice seitan to the pan with the mushrooms. You can also set the mushrooms to side if that’s easier (or cook both in tandem in separate pans). Cook the seitan on both sides, for about 5 – 10 minutes. This is mostly just to heat up the seitan and add a bit of texture.
- Add the vegan mozzarella on top of the warm seitan slices. It should start to melt.
- This step is optional, but highly recommended – toast your bun! You can do this with or without butter (butter not factored into these calories), on broil in your oven. It usually only take 3 – 5 minutes, but keep a very watchful eye on it because bread can burn quick.
- Place the seitan, mozzarella, and mushrooms on your bun and enjoy!
