One of the best ways I found to increase my veggie intake was to explore new kinds by making one day a week vegetarian. I explored new recipes, which had me trying new vegetables or preparing them in new ways. I still like my lean proteins, but I also look forward to my veggie days too.
One of my quick and easy faves is a grilled veggie sandwich. Sliced Eggplant, sliced zucchini, sliced onion, sliced bell pepper, grilled (mine is on the George Foreman). Put it on some whole wheat bread, roll or pita with a slice of swiss cheese and some hummus or roasted pepper spread.
