### Flavorful Chicken Tacos Recipe

**Ingredients:**

- **Chicken and Marinade:**
  - 5-6 chicken thighs, boneless and skinless
  - Juice of 2 limes
  - 3 cloves garlic, minced
  - 1/4 cup fresh cilantro, chopped
  - 1 tsp cumin
  - Salt and pepper to taste

- **Sauce:**
  - 4 chile guajillos, dried
  - 3 Roma tomatoes
  - 1/2 tsp smoked paprika
  - 1/2 tsp chipotle powder
  - Salt to taste

- **Vegetables:**
  - 1 white onion, sliced
  - 1/2 green bell pepper, sliced
  - 2 cloves garlic, minced
  - 1-2 tbsp oil (olive or vegetable)

- **Extras:**
  - Fresh cilantro, chopped (for garnish)
  - Lime wedges (for serving)
  - Sour cream or chipotle mayo (for serving)
  - Avocado, diced (optional)
  - Corn or flour tortillas

**Instructions:**

1. **Marinate the Chicken:**
   - In a bowl, combine lime juice, minced garlic, chopped cilantro, cumin, salt, and pepper. Add the chicken thighs and toss to coat evenly. Cover and refrigerate for at least 1 hour, preferably overnight.

2. **Prepare the Sauce:**
   - Remove seeds from the chile guajillos and soak them in hot water for about 20 minutes until they soften.
   - In a blender, combine the softened guajillos, Roma tomatoes, smoked paprika, chipotle powder, and some of the soaking liquid. Blend until smooth. Taste and adjust salt as needed.

3. **Cook the Chicken:**
   - In a large skillet, heat 1 tbsp oil over medium heat. Remove the chicken from the marinade (discard any excess marinade) and sear the chicken thighs until golden on both sides, about 6-8 minutes per side.
   - Pour the guajillo sauce over the chicken, reduce the heat to low, cover, and let simmer for 20-30 minutes, or until the chicken is tender and fully cooked. Shred the chicken in the sauce and keep warm.

4. **Sauté the Vegetables:**
   - In another skillet, heat the remaining oil. Add the sliced onion, green bell pepper, and minced garlic. Sauté until the vegetables are caramelized and slightly charred, about 8-10 minutes.

5. **Assemble the Tacos:**
   - Warm the tortillas on a skillet or directly over a flame until slightly charred and pliable.
   - Spoon the shredded chicken mixture onto each tortilla. Top with the sautéed vegetables, fresh cilantro, diced avocado (if using), a dollop of sour cream or a drizzle of chipotle mayo, and a squeeze of lime juice.

6. **Serve:**
   - Serve the tacos hot with extra lime wedges on the side for squeezing.
