This vegan Reuben sandwich is a great way to showcase homemade fermented foods. Pretty much everything in it is fermented. The sauerkraut, rye bread, tempeh… it’s all fermented!
A Fermenting Foodie Sandwich
I’m hoping that this simple sandwich will encourage you to try making some of your own fermented foods!
- Sauerkraut is a very easy ferment for beginners. All it takes is cabbage, salt and patience.
- Dijon mustard and probiotic ketchup are both good for getting a bit more probiotics into your diet.
- Sourdough rye is a no-kneed bread that has an amazing flavour.
- Tempeh is definitely more advanced ferment, but it’s still very fun to make! Why not try something new?

Instructions
- Mix together the ingredients for the Russian dressing in a small bowl.
- Lay out two pieces of bread for each sandwich on a cookie sheet, and toast under the broiler until they are just starting to brown.
- Spread a thin layer of Russian dressing on each slice of bread (top and bottom slices) .
- Cover the bottom slice of bread with a slice of tempeh, followed by 2 tbsp of sauerkraut, and top with a slice of cheese.
- Place the second slice of bread on top of the cheese, then butter the top of the sandwich.
- Broil on low until the bread is well toasted.
- Serve immediately with a large fermented dill pickle and a handful of potato chips.
Notes
- Swiss cheese is traditional in a Reuben sandwich, so if you’re a vegetarian feel free to replace the vegan cheese with Swiss cheese, and the margarine for butter.
- I’ve included my favourite vegan alternatives in the recipe above, however, feel free to replace them with your favourites.
