Chicken-Chorizo Burgers with Avocado Mayonnaise

Ingredients

• Mayonnaise:
• 1/3 cup fat-free mayonnaise
• 1/4 cup fresh cilantro leaves
• 2 tablespoons fresh lime juice
• 1/4 teaspoon salt
• 1/2 ripe peeled avocado, seeded
• Burgers:
• 1/2 pound Spanish chorizo sausage (such as Usinger's)
• 1/4 teaspoon salt
• 5 (6-inch) corn tortillas, torn into bite-sized pieces
• 1 1/2 pounds skinless, boneless chicken breasts, coarsely chopped
• 1 jalapeño pepper, seeded and chopped
• Cooking spray
• 8 (2-ounce) onion rolls, toasted
• 8 (1/4-inch-thick) slices tomato

Preparation

1. Prepare grill or broiler.
2. To prepare mayonnaise, combine first 5 ingredients in a food processor; pulse 10 times or until combined. Cover and chill mayonnaise mixture.
3. To prepare burgers, remove casings from sausage. Place sausage, salt, tortillas, chicken, and jalapeño in food processor; process 30 seconds or until mixture is coarsely ground. Divide mixture into 8 equal portions, shaping each into a 1/2-inch-thick patty.
4. Place patties on a grill rack or broiler pan coated with cooking spray; cook 7 minutes on each side or until done.
5. Cut rolls in half horizontally; spread 1 1/2 tablespoons mayonnaise mixture over top half of each roll. Place tomato slices on bottom halves of rolls; top each with 1 patty and top half of each roll.
