Hamburgers with avocado and greens

Ingredients:

For the Green Goddess dressing:

• 1/3 cup natural low-fat yogurt
• 2 tablespoons low-calorie mayonnaise
• 1 tbsp. freshly squeezed lemon juice
• 1 teaspoon Worcestershire sauce
• 1/4 cup chopped fresh chives
• 2 tbsp chopped fresh basil
• Coarse salt and freshly ground pepper

For hamburgers:

• 650 g ground beef, preferably neck
• Coarse salt and freshly ground pepper
• Vegetable oil, for grilling
• 4 whole grain buns, cut horizontally into halves
• Red leaf lettuce leaves
• 2 plum tomatoes, cut into slices
• Alfalfa shoots
• 1 avocado, halved, pitted and sliced

Preparation:

1. Preheat grill to medium-high heat.
2. Prepare the Green Goddess dressing: Blend the yogurt, mayonnaise, lemon juice, Worcestershire sauce, chives, and basil in a blender, adding salt and pepper to taste. Transfer the dressing to a bowl, cover, and refrigerate until ready to use.
3. Prepare hamburgers: Form the minced meat into four round patties, each weighing 160 grams and about 2 cm thick. Using your thumb, make a 1/2-inch (1.2 mm) indentation in the center of each patty. Season both sides of the patties with salt and pepper. Lightly oil the grill grates, place the patties on the grates, indented side down, and cook until charred, about 5 minutes. Flip and continue cooking until slightly firm, about 3 minutes more. The patties will be medium-rare. Transfer the patties to a platter and let them rest for 5 minutes. Place the buns, cut side down, on the grill and cook until golden brown, about 1 minute.
4. Layer lettuce leaves, tomato slices, patties, alfalfa sprouts, and avocado on the bottom halves of the buns. Drizzle with the dressing and top with the top halves of the buns.
