What makes an ordinary cheeseburger bistro? Perfectly grilled beef patties topped with Swiss cheese, crisp romaine lettuce, juicy tomato and thick slices of grilled sweet onion tucked between lightly toasted crusty rolls.

Bistro Cheeseburger

1 1/2 pounds ground beef
4 slices sweet onion (1/2-inch)
Vegetable oil
8 slices Swiss cheese
1/4 cup mayonnaise
1 tablespoon Dijon-style mustard
4 crusty rolls, split, toasted
Romaine lettuce, tomato slices

1. Lightly shape ground beef into four 3/4-inch thick patties.
2. Brush onion with oil.
3. Place patties in center of grid over medium, ash-covered coals; arrange onion around patties. Grill, uncovered, 13 to 15 minutes to medium (160°F / 70°C) doneness, until patties are not pink in center and juices show no pink color and onions are tender, turning occasionally. Season with salt and pepper after turning. About 1 minute before patties are done, top each with 2 cheese slices.
4. Combine mayonnaise and mustard; spread on top halves of rolls.
5. Serve burgers and onion in rolls with lettuce and tomato.

Makes 4 servings.
