Soak chia seeds in half the amount of yogurt or about 100 ml for at least 2-3 hours, it is best to leave them overnight.
The next morning in a blender put the other half of the yogurt, add the banana, blueberries and almonds and blend briefly. Pour the fruit part of the pudding to the bowl with the chia seeds and yogurt which have already gotten a nice pudding-like structure.Decorate as desired. I put fresh strawberries and some more sliced almonds.
