In a blender, add all the shake ingredients and the protein powder. Blend until frothy. Soy milk does that.
If you have created a jar for the week, use about 8 tbsps of the powder to make an equivalent of the 1 portion above. You may need to adjust the quantity of soy milk (if you use 500ml of soy milk, the total shake comes to 30g of protein, 36g net carbs, 10g fiber, 26g fat - the healthy unsaturated type from soy) or if you want a low cal one, just add water (it may change the taste and reduce the protein content).
A good tip is you can split this shake into 2 shakes of 4 tbsp plant protein powder, because 200ml is quite a small portion, and when blended it makes it a really light beverage. That will give you an additional 6g of protein.
If you find this too bitter or really nutty in taste, add 1 more tbsp of maple syrup or a sweetener of your choice.
