Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Season chicken thighs with salt and place on a baking sheet. Roast for 25-30 minutes until golden and nearly cooked through.
  2. Step 2: In a large skillet, sauté 1 diced onion and 3 minced garlic cloves over medium heat until translucent (5 minutes). Add 400g diced tomatoes, 1/4 cup chopped cilantro, and 1 tbsp lime juice. Simmer for 15 minutes until sauce thickens.
  3. Step 3: Shred cooked chicken into bite-sized pieces. Add to the skillet and stir to coat in the sauce. Cook for 5 minutes until chicken is fully cooked and tender.
  4. Step 4: Warm tortillas in a dry skillet or microwave. Assemble tacos with chicken, avocado, jalapeño slices, and a drizzle of sauce. Serve immediately.
