Slow Cooker BBQ Chicken Sandwiches

Ingredients:

• 6 large boneless, skinless chicken thighs (about 1 kg)
• 2 tsp ground cumin
• 1 chipotle pepper in adobo sauce, chopped + 3 tablespoons jarred adobo sauce
• 1 cup canned mashed fried tomatoes
• Half a medium onion, grated
• 2/3 cup ketchup
• 3 tbsp + 1 tsp brown sugar
• 1/4 cup apple cider vinegar
• 1 tbsp Worcestershire sauce
• 1/4 cup vegetable oil
• 2 cups shredded red cabbage
• 2 radishes, thinly sliced
• 3 green onions, thinly sliced
• 1 avocado
• 4 sesame hamburger buns
• 8 thin slices Monterey Jack cheese (about 110 g)

Preparation:

1. Sprinkle the chicken with salt and cumin; transfer to a 6-8 quart slow cooker. Add the chipotle and adobo sauce, tomatoes, and onion; stir to coat. Cover and cook on low for 6 hours.
2. Transfer the chicken to a plate. Pour the liquid into a separator. Then pour the broth into a small saucepan, reserving any fat in the jug (or use a spoon to skim the fat from the surface of the broth). Add the ketchup, 3 tablespoons of brown sugar, 2 tablespoons of apple cider vinegar, and Worcestershire sauce to the saucepan. Bring to a boil, then reduce the heat and simmer until the sauce thickens slightly, 3-5 minutes.
3. Meanwhile, in a large bowl, combine 2 tablespoons vegetable oil with the remaining 2 tablespoons vinegar and 1 teaspoon brown sugar. Add the cabbage, radishes, green onions, and 1/2 teaspoon salt; toss to combine.
4. In a large nonstick skillet, heat the remaining 2 tablespoons of vegetable oil over high heat. Add the chicken and cook, stirring occasionally and breaking it up with tongs or a fork, until browned and crispy, 3-5 minutes. Set aside 1/2 cup of the sauce and combine the rest with the chicken; season with salt to taste.
5. Preheat the oven to broil. Slice the avocado. Place the bottom halves of the buns on a baking sheet; top with the chicken and cheese. Broil in the oven until the cheese is melted, about 2 minutes. Top with the cabbage and avocado, and cover with the bun tops. Serve with the remaining sauce.
