So what are they gonna do with all that canned and prepackaged food in prison? Make some seitan n' dumplings. It's super easy. You don't even need a recipe, right? Just make yourself some seitan stew using broth, veggies, and seitan. I like to thicken the mix with a little cornstarch so I have a nice thick stew. I used about 3T total for a 32 oz container of no-chicken broth. While the concoction is all nice and bubbly, plop your dumpling batter in the mix. Cook for 10 minutes covered, then another 10 minutes and you have a filling dinner.
Since I'm no recipe master, I used Bisquick-(accidentally vegan!) to make the dumplings.
