Student cookbook: Blue cheese and black pepper burgers

There are so many ready-made burgers around you may not see the point of making your own, but they're healthier and you can be a bit creative with them. The ideal way to cook them is on a George Foreman-type grill, but you can also pan-fry them. Serves: 4 Cooking time: 15 mins 500g lean mince 75g blue cheese such as stilton, rind removed, and crumbled 1 tsp fresh rosemary, finely chopped (optional) Salt and freshly ground black pepper A little olive oil 2 tomatoes, finely sliced A small red onion, finely sliced, or some finely shredded spring onions A small pack of watercress or salad leaves 4 x burger buns Tip the mince into a bowl and add the crumbled cheese, rosemary if you're using it, a little salt and a generous amount of freshly ground black pepper. Mix well with a fork or your hands then divide into 4, rolling each part into a ball then patting each one into a burger shape. Heat up your grilling machine or pan for a few minutes while you get the trimmings ready to top the burgers. Rub a little oil into both sides of each burger and cook for 2-3 minutes. Split and toast the buns if you like them toasted. Lay the burgers on the lower half of the buns, top with the sliced tomato, onion and a small handful of watercress or other salad leaves, trickle over a little olive oil, season and top with the other half of the bun.
