Fantastically Refreshing Strawberry Water
This is so easy it almost doesn't count it as a recipe. You blend a handful of strawberries, fresh or frozen, in some water. That's it. It makes a quick flavoured water which is great if you are like me and cannot stand the taste of city water but also can't afford (and are morally opposed) to buying bottled water. And you get some bonus nutrients from the strawberries. This is way better than drinking those chemically flavoured waters or those fake juices you can buy in the store.
For a more store like flavoured water experience, try straining out the seeds.
