I visited a friend in Santa Monica this spring and we went to the local Sunday market.  We both got breakfast at a booth serving vegetarian sandwiches, grilled to order.  The sandwich was quite tasty, but the best part was the water jug.  They had packed a healthy handful of fresh herbs into a water jug with ice.  Simple and no frills but it turned a 6oz paper cup of water into an event.

1 gallon water
10 sprigs of fresh sage leaves
10 sprigs of fresh mint leaves

Place herbs in a pitcher with water and ice.  Easy!
