For best results, use chicken thighs instead of breasts as they are more forgiving and stay moister during the long cooking process. To customize the heat level, adjust the amount of cayenne pepper in the seasoning or add chopped jalapeños. Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days and reheated in the microwave, skillet, or crockpot. Use leftover fajita mixture in tacos, burrito bowls, salads, nachos, or quesadillas for a quick and easy meal.
