Avocado-Bun Turkey Sliders

Ingredients

• 1 small red onion, quartered and sliced
• ½ cup white vinegar
• ½ cup water
• 2 teaspoons sugar
• ¾ teaspoon salt, divided
• 1 pound lean ground turkey
• ¼ cup chopped fresh cilantro
• 2 teaspoons ground cumin
• ¾ teaspoon ground chipotle pepper, divided
• 6 teaspoons mayonnaise
• 6 ripe baby avocados, halved, pitted and peeled
• 2 Roma tomatoes, cut into 6 slices each
• 3 leaves green-leaf lettuce, halved
• ½ teaspoon sesame seeds

Directions

1. Preheat oven to 350 degrees F. Coat a large baking sheet with cooking spray.
2. Combine onion, vinegar, water, sugar and 1/4 teaspoon salt in a small saucepan. Bring to a boil. Remove from heat and let stand for at least 15 minutes. Drain.
3. Gently mix turkey, cilantro, cumin, 1/2 teaspoon ground chipotle and the remaining 1/2 teaspoon salt in a medium bowl. Form into 6 oval-shaped patties the size of your avocados (about 2 by 3 inches) and place on the prepared baking sheet. Bake until an instant-read thermometer registers 165 degrees F, about 20 minutes.
4. Meanwhile, stir together mayonnaise and the remaining 1/4 teaspoon ground chipotle in a small bowl.
5. To assemble, cut a thin slice from the bottom half of each avocado to make it more stable. Top an avocado half with 1 teaspoon of the mayonnaise mixture, about 1 tablespoon of the pickled onion, a burger, 2 tomato slices, lettuce and another avocado half. Sprinkle each slider with sesame seeds.
