Most of us choose what to eat by habit.
Today, go to the market with the best produce in town and pick out a new vegetable and a new fruit to try. As the nice produce person for help in choosing and how to prepare your new treat.
Simple is good.
Vegetables that just need to be steamed and have a little lemon juice squeezed over them are great. Try something else in a family of food you like. Enjoy broccoli? Ever try the romanesque variety? It's Fibonacci-licious.
Most fruit just needs to be cut up, so that's easy. Try something peculiar looking if you're adventurous today. Or if not, just hold an apple tasting.
