Ingredients:

• 2 teaspoons olive oil
• 1/2 cup minced scallions
• 3/4 teaspoon salt
• 1/4 teaspoon freshly ground black pepper
• 3 tablespoons reduced-fat sour cream
• 4 teaspoons Worcestershire sauce
• 1 1/2 pounds lean ground turkey
• Nonstick cooking spray
• 3 ounces blue cheese, crumbled
• 6 whole wheat hamburger buns, split
• 2 firm, ripe tomatoes, sliced 1/4-inch thick
• 1 just-ripe avocado, thinly sliced
• 1 medium red onion, thinly sliced

Directions:

1. In a small skillet, warm the olive oil over medium heat. Saute the scallions until just softened, about 2 minutes. Transfer to a medium bowl, season with the salt and black pepper and let cool. Stir in the sour cream and Worcestershire sauce; add the turkey and mix gently until just combined. Form into 6 patties.
2. Prepare the Portable Kitchen for direct grilling. Mist hinged grid with nonsticking cooking spray and cook burgers 5 minutes. Turn and grill until almost cooked through, about 3 minutes more. Top each burger with some of the blue cheese; cook 1 to 2 minutes more or until burgers are just cooked through and cheese is melted. Grill buns until just crunchy.
3. Arrange burgers on buns and top with sliced tomato, avocado, and red onion.
