Breakfast. I never have time, nor appetite, for breakfast before work. So I have a smoothie & take it to work. Prepare the night before, stick in the fridge, then blend in the morning. Takes 30 seconds. My current favourites are:
Half an avocado, small banana, 5 tsp raw cacao powder, 3 tsp chia seeds, about half a cup orange juice, fill up with water.
2 apples (cored), half a cup of blackcurrants, half a cup of apple juice, 1 inch slice of lemon, fill up with water.
Watermelon (lots), sprig of fresh mint, couple of inches of cucumber, fill up with water.
Mind you, I don't have much of a sweet tooth - I like my fruit sharp & unsweetened.
