Preparation: mix the oats with the almond milk, vanilla and linseed oil. Mash the banana, mix with the lemon juice, add to the mixture. Rehydrate the goji berries in a little water or orange juice, add to the Bircher. Sprinkle with chopped almonds. Leave to stand so that the flakes absorb the milk.
Variations: you can replace the goji berries with other red fruits or sultanas. Almond milk can also be replaced by simple cow’s milk.
