Roll it in heaps of salt and pepper, and seal it in a hot pan really quickly, just roll it til its brown all over.
Put it straight in the oven and cook it on 180 for about 10 mins (depending on how pink you like it and how thick it is)
Rest it for a good 10 mins
Then just slice it and serve it with a salad or steamed veg.
Roll in or marinade in lemon zest, garlic, pepper, rosemary, thyme, sumac and sesame seeds that have all been bashed a bit in a mortar and pestle (add a bit of lemon juice and olive oil if you prefer to marinade it) for a Greekish / Middle Easternish flavour. Really good with tzaziki or hummus.
Or just rosemary and garlic.
Or sesame seeds, soy and ginger with an Asian noodle salad.
Also really good barbecued whole, then sliced (rather than roasted)
