112g of u/u Huel
4g Huel chocolate flavour
6g of cocoa
80g of banana (from a stash of frozen cut bananas in a ziplock in my freezer)
15g of almond butter
300ml of water
Ice until the whole mixture reaches about 600ml
All in the shaker and blended with an immersion blender directly in the shaker. So delicious - though significantly more calories than Huel on its own 
One of my combinations I came up with a couple weeks ago.
16.9oz (500ml) of water
100g (2x v2 scoops) of Vanilla Huel
2x servings (2x rounded teaspoons) of Folgers instant coffee
1x serving of Caramel Huel Flavor Boost.
You can probably use decaf coffee if you prefer. The reason I use 2 servings is because the directions indicate that a serving is used with 6oz (177.5ml) of water.
