Steaming is a great way to cook veg. It keeps in so many of the vitamins lost by boiling, and can be done in stacked steamer baskets. Best of all, though, it only takes up one ring of your cooker! The butters are easy to make and can be done way ahead. Keep any leftovers in your freezer and use a slice when you cook a steak. Don't cook all the vegetables or you'll have far too many – just pick your two favourites.
