I like Jamie Oliver. There I said it. Seems like a top chap to me. I know people have mixed views and if, like my brother, you're less than keen on the personality I'd still recommend you try out some of his recipes.
For the most part they're pretty quick and straightforward (maybe not 30 minutes though, eh Jamie?!) but the best thing about them is that every one I've made has worked perfectly and tasted delish.
Last night we had tuna steak, with asparagus and cherry tomatoes and a basil creme fraiche. True to form it was really simple and totally scrumptious. Jamie's recipe is here.
