Add the sun-dried tomatoes and walnuts to a food processor and pulse until you reach a paste-like texture. Add all the remaining ingredients to the food processor and pulse, stopping to scrape the sides as needed until combined into a crumbly dough.

Pinch off some of the dough and roll into a vegan meatball about the size of a golf ball and set aside on a plate or dish. Repeat until all the dough is used up and you have made about 20 meatballs.

Fill a large pot with several inches of water and place a steamer basket inside. Bring the water to a boil, then add the meatballs to the steamer basket. Cover and steam for 25 minutes, gently turning the meatballs halfway through, or until their internal temperature reaches at least 160°F (71°C) when tested with an instant-read thermometer. If the temperature goes higher, that's perfectly fine—you can't really oversteam seitan.The meatballs will expand a bit when they steam. Once the steaming is done, you can either prepare them right away (see below), or allow them to cool completely and store in an air-tight container in the fridge for up to 5 days, or freeze for later.

Steaming the seitan is what gives it the perfect texture. Once they are steamed you can basically treat them as if they were raw meatballs and pan-fry them before serving.To do this add 1 tablespoon of oil to a large skillet over medium-high heat. When hot, add the meatballs and fry a couple of minutes per side, turning as needed until they are golden all over and heated through. Serve with dipping sauce, add to a tomato sauce, or enjoy them any way you please. * Learn my secret tricks to making perfect seitan in my free masterclass. Click here to learn more and register.
