I recently started doing this too! The easiest way ever is V8, honestly. You get all the good stuff for you without having to eat it or convince yourself it tastes good with cheese/dressing/bread. And its way cheaper than buying that many veggies. Also, I started using the Juice Plus 'Ultra juice' supplement which is bi-layered tablets. I used to have a terrible immune system (I was sick like every other week). The ultra juice gives me I think 6 servings of the nutrients in fruits and veggies released throughout the day. I haven't been sick in months. Those two get me by without spending my calorie limit
