A breakfast that you have to prepare the night before can sound tedious but this takes just a few minutes and involves no mess. Combine the oats, chia seeds, milk, honey and vanilla the night before and leave in the fridge overnight to develop into a kind of pudding then add the lemon juice, seeds and fruit the next morning. When I'm feeling really lazy I only combine the oats, chia and milk the night before which takes no more than two minutes.
Anna Jones uses white peaches in her recipe which would be divine but they aren't always in season. Frozen fruit works really well but my all time favourite combination is warmed frozen raspberries and fresh mango. Cherries, blueberries, apples, pears; almost any fruit works really.
As an aside, I recently bought a Gelindo citrus squeezer from Amazon which has made one of my least favourite kitchen tasks, juicing lemons, effortless. It's well made, sturdy and most importantly, easy to clean. I couldn't recommend it more.
