Straight up vegetables

So I'm getting a little jump start on my healthier lifestyle.  I've eaten just one too many doughnuts to justify eating "anything I want".  I'm feeling the flab and I'm not happy about it.  So over the weekend I went to a market to buy only fruits and vegetables.  Since I am not used to eating just vegetables I am not really going by any recipes quite yet.  I'm just throwing whatever sounds good together.  So today it was a bowl of radishes and then I cooked some sweet potatoes with shiitake mushrooms.  That's it and that is all I plan on eating for the day.  Sounds bland and boring but it is a start.
