Day 3: If you're trying to build a five-a-day habit (or even better, more!), summer is the time to do it. My fridge is overflowing with fresh tasty produce: Lettuce and green onions from the garden, fresh-picked strawberries from the farmers market, melon, every color of pepper, cucumbers -- you get the idea.

An easy place to start is incorporating just one fruit or veggie into every meal or snack. (If you're not a snacker, aim for two servings at every meal.) Today, I ate two small plums with my breakfast smoothie, a whole bunch of carrots and cucumbers with hummus for lunch, and I had a big bowl of fruit salad -- cantaloupe and watermelon -- with my grilled turkey sandwich (also topped with romaine and tomato) for dinner.

I don't like to spend a lot of time at a hot stove in the summer, so these simple meals worked perfectly for me.
