I just put them in a griddle pan with a bit of fry light, they dont take long. Frying pan is just as good but I like the pretty chargrilled lines on mine
Your veg doesn't have to be boring i sometimes stir fry my veg with a little paprika, garlic and tumeric or some fresh chillis and it gives it a really nice taste and smells really good! Orr if you're boiling them, adding a vegetable (or other) oxo cube and a little sweetner to the water gives them a nicer flavour.
