Ingredients (Serves 4)
Mix together the beef, red pesto or sundried tomato sauce, onion and garlic in a bowl and season well with salt and freshly ground black pepper. Using wetted hands to prevent sticking, divide the mixture into 4 and shape each portion into a burger. Chill for about 20 minutes.
Cook the burgers on the barbecue or in a preheated griddle pan for 6-8 minutes on each side for well done, or to preference.
Meanwhile, toss the watercress in the French dressing. Cut the rolls in half and place on the barbecue to toast.
Lift the cooked burgers onto the toasted bun bases and place 1-2 slices of tomato on top. Crisscross 2 Brie slices over the top and pop under the grill until the cheese is just beginning to melt. Serve with the dressed watercress on the side.
