Stilton Burgers

Manami's Note:

Send the last lazy days of the season out in style by grilling peak-quality meats, fruits, fish and even vegetables. This burger is truly beautiful and it tastes superb, with the cheese melting over the beef with caramelized onions atop - with fresh green lettuce and sliced tomato on the bottom - it looks very pretty.
