Cut the potato into cubes (I leave the skin on but you can peel it if you want). Cook in boiling water for 10 minutes, or until fork-tender.
Transfer cooked potato to a medium bowl, and mash it together with vegan butter, then let cool completely.
Meanwhile, combine chickpea flour and water to create the 'egg' mixture. Prepare flour and rice puffs for breading.
Once the potato is cool, add flour and seasonings, mixing well to incorporate. Take around 2 tbsp of the mixture, flatten it with your palm and place the cheese in the middle. Roll it to get a smooth log shape. Repeat with the rest of the mixture.
Lightly coat each piece in flour, the 'egg', then the rice puffs. Pack the rice puffs in tightly, making sure to cover as much surface as possible.
Prepare a pot with at least 2-inches of cooking oil. Once it is hot, reduce to medium-low. Fry the croquettes in batches for 3-4 minutes, turning it around to make sure it cooks evenly. Once it's golden brown, remove from the oil and place on a wire rack to drain.
Serve immediately with sauce of your choice.
