Tangy, melting blue cheese gives these burgers a surprise centre – a real treat for a midweek meal.
*Stilton or Roquefort are good blue cheese choices. Alternatively use Gruyère or mature Cheddar.
*Top with sliced gherkins, if liked, and serve with extra salad and home-made oven chips. Cut peeled or scrubbed potatoes into thick wedges, then toss in vegetable oil, to coat them lightly. Sprinkle with seasoning and dried herbs, if liked. Bake for 45 minutes in a hot oven, preheated to 220°C (gas 7).
