Link to Vegan Tempeh Reubens recipe.
GV comments: What screams "Reuben" in a Reuben sandwich is the combination of rye bread, sauerkraut, and salty cheese. So vegans can substitute tempeh for corned beef and vegan cheese for dairy cheese, and you still get that scream. I love this recipe because it boils the tempeh in a rich oniony, galicky, soy broth, so you get a depth of flavor from the tempeh layer of the sandwich--it's not just filling up space.
Timing: About 45 minutes, including cooling time for the tempeh, but you could make the tempeh the day before or earlier in the day, then the sandwiches would come together in less than 15 minutes at dinnertime.
Nutrition: With vegan mayo, ketchup, and cheese, this isn't whole-food unprocessed. Look for whole-grain rye bread (many are made with refined rye flour, and some have refined wheat flour mixed it).
Rye has gluten.
