Stilton and toasted walnut burgers with grilled tomatoes and spicy leeks

This was very tasty - basically a very refined cheeseburger.

I loved the leek mixture, the cheese/nut mixture, and the addition of walnuts to the burger itself. I could have done without the grilled tomatoes and the watercress - maybe I'll make a side salad of them next time.

I made quite a few ingredient substitutions: scallions for leeks, Danish blue for Stilton, balsamico for the port wine, hamburger buns instead of multigrain bread. I used a generic red wine. I don't have a clue what Paul Prudhomme's Vegetable Magic is, so I seasoned to taste. I added a bit of thyme to the cheese/nut mixture.
