Preheat the oven to 200°C / 400F°.

Boil the potato until soft. Drain and mash. Set aside to cool.

Meanwhile, combine the beans, one quarter of the onion (roughly chopped), 3 roughly chopped cloves of garlic, the soy sauce and vegetable stock in a blender or food processor and blend until smooth.

In a bowl, combine the vital wheat gluten, paprika, oregano, basil, nutritional yeast, mashed potato and liquid mixture. Mix to combine then use your hands to mash the mixture together into a dough.

Tear off portions of the dough and roll them into meatballs. Place them on a lightly greased or paper-lined pan and bake for 20 minutes, flipping them over at 10 minutes. You can eat them still warm from the oven or you can let them cool and reheat them in the sauce later. I find that letting them cool helps them firm up to a more meaty texture.

Heat a large pan over medium-high heat and dice the remainder of the onion. Cook the onion and remaining 2 cloves of minced garlic in a splash of water until soft. Add the red pepper and fry until soft. Add the sauce, salt, pepper and meatballs. Simmer for a few minutes until the meatballs are heated through then serve.
