Wash the lenses thoroughly and soak in the 250ml water for at least 2, more likely 4 hours.
Puree the lentils with the water. It doesn't have to be very fine, just so that it creates a mass.
Mix in all the other ingredients and let it soak for an hour.
The soy granulate absorbs the excess water and so the mass becomes firm and malleable. If it is still too soft, add a little more (1-2 tbsp) soy granulate and let it soak for 15 minutes.
Slowly bake the meatballs / patties / party cakes on medium heat, they should be well cooked through.
There will be about 6 normal meatballs.
The meatballs taste warm and cold, cold they are really nice and firm to the bite.
I am very enthusiastic about the mass and will soon test whether you can make a kind of meatloaf from it.
The soy granulate can be replaced with chickpea flour.
