To impress company, upgrade to specialty bistro-style burgers. Try adding sun-dried tomatoes and feta cheese to the meat, and topping with balsamic vinegar-glazed onions. Or baste thick slices of sweet red onion with a rich, smoky barbecue sauce, grill them, and top burgers with the onion and a dollop of mayonnaise infused with Roquefort cheese. For an ooey-gooey – but oh, so tasty – burger, pile it high with grilled green bell pepper and onion strips, then smother it in melted processed cheese (such as Cheez-Whiz) before putting on the top part of the bun. Gourmet burger recipes abound, so look around: try typing “gourmet burger recipe” into a search engine and marvel at the possibilities spread out before you!
