I attempted a variation on @jmjam19's recipe. I don't recommend anyone try them as they did not hold together at all. I tried to form them into bars but they just crumbled apart once they cooled. I didn't try freezing them like jmjam19 did, so I can't comment on what effect this would have. @jmjam19, do your balls stay together even after thawing to room temperature?
300g U/U Huel
13g vegan butter (used Sainsbury's Freefrom spread)
2 tsp olive oil
25g almond butter (from Bulkpowders)
250ml hot water (left in the kettle for a couple of minutes post boil)
Makes 8 bars. Each bar is 200 cal, with 20.4g carb (of which .5g is sugar), 8.8g fat and 12.2g protein.
I simply put all ingredients in a bowl and mixed together.
Were I to try this again I would probably use quite a bit more Vitafiber as it is a good binder. Also, most recipes say that it should be mixed with water and heated until it dissolves in. I didn't do this. I don't know if it is necessary to "activate" the Vitafiber or not.
