It's all about the spices like mentioned above. Roast 'em, toss 'em in a frying pan, grill 'em, whatever works. Add them to things you already know you like after the preparation phase and you'll find yourself ingesting less meat/carbs gradually. Always get fresh vegetables and fruits but don't over pay. Hit up a farmer's market at any given opportunity and get a week's worth of food for thirty bucks.

Get some tasty healthy snacks too! Clif bars, hummus, dried fruit, snap peas, mandarin oranges, and baby carrots are just dandy.
