How to eat more vegetables:
Step one: Get rid of your ordinary carbs: Rice, bread, potatoes, pasta.
Step two: Eat much, much more meat.
Step three: Eat lots of vegetables.
Result: Your diet now consists of protein and vitamins, with all the minerals and oils your body needs.
Edit: But that's a bit boring, so yeah... Just buy vegetables, cook/steam them, and eat them. Spices work miracles if it's just too bland. Don't overcook, keep a bite, but don't undercook.
