Roast Chicken-Chipotle Nachos with Cilantro-Avocado Crema

Ingredients

• 1/2 cup chopped onion
• 1 tablespoon olive oil
• 1/2 teaspoon cumin seeds
• 1/2 teaspoon dried oregano
• 1 to 2 canned chipotle chilies, chopped
• 2 tablespoons tomato paste
• 1 tablespoon white wine vinegar
• 2 cups bite-size shreds skinned cooked chicken (see notes)
• 24 corn tortilla chips (2 3/4 in. wide)
• 1 1/2 cups shredded jack cheese (6 oz.)
• Cilantro-Avocado Crema (recipe follows)
• 24 fresh cilantro leaves

Preparation

1. 1. In a 2 1/2- to 3-quart pan over medium-high heat, frequently stir onion in olive oil until onion begins to brown, 4 to 7 minutes. Add cumin seeds and oregano; stir until fragrant, about 30 seconds. Add chilies, tomato paste, vinegar, and 1/2 cup water; bring to a boil, then reduce heat and simmer gently, stirring often, to blend flavors, about 5 minutes. Add chicken and stir until hot.
2. 2. Meanwhile, arrange tortilla chips in a single layer in a 12- by 17-inch pan. Sprinkle equal portions of cheese on each chip and spoon about 1 tablespoon chicken mixture on top.
3. 3. Bake in a 450° regular or convection oven until cheese begins to bubble, about 3 minutes. With a spatula, carefully transfer tortilla chips to a platter. Top each with 1 teaspoon Cilantro-Avocado Crema and garnish with a cilantro leaf. Serve warm.
4. Cilantro-Avocado Crema. In a small bowl, mix 1/3 cup finely diced firm-ripe avocado, 2 tablespoons sour cream, 1 tablespoon finely chopped fresh cilantro leaves, 2 teaspoons lime juice, and 2 teaspoons milk. Add salt to taste. Makes about 1/2 cup.
