For the last year of so I've been working out at the gym after work (the gym's at work so it's convenient and free) and immediately afterwards I have a Clif Builder's bar, take a shower, then I go back to my office where I have a smoothie for "supper." Most of the time it consists of water, a meal-replacement powder, ground flax seed, a banana and some frozen strawberries.

It's occurred to me that I should probably have a bit more variety in the fruit add-ins. For example, blueberries could be a good substitute for the strawberries, but I'm wondering if anyone out there uses anything really new / interesting / healthy that would also work.

TIA
