Alanna over on A Veggie Venture just had a great post about how to eat more vegetables. I think it's really easy to grab something on the go and it might taste good, but not be great for you. And with so many delicious vegetables and fruits why not eat more?
I think the best way to eat more veggies is to get more connected with your food. If you don't have space for a garden (I didn't last year) try joining a CSA (Community Supported Agriculture). Knowing where your food is coming from and trying new veggies will definitely get you eating more. And if you know you have another delivery of veggies on their way you have some extra motivation to eat up!
If you do have a little room, even just a porch like me, try planting a pot with a veggie plant. Watching it grow, tending to it, seeing how awesome it is when seedlings come up and then get flowers and finally food is so rewarding. Oh - and homegrown just tastes so much better you'll really look forward to it!
