2. Can I use pre-cut fajita vegetables, or should I chop them myself?
You can use pre-cut fajita mix (like bell peppers and onions) to save time, but fresh-cut works just as well. If using fresh, slice onions into wedges and peppers into strips (about ½-inch thick). For extra tenderness, lightly char them before adding to the slow cooker.

3. How long should I cook the chicken fajitas in the slow cooker, and at what temperature?
Cook on LOW for 4–5 hours or HIGH for 2–3 hours, depending on your slow cooker’s size. Stir occasionally to prevent sticking. The chicken should reach 165°F (74°C) internally. If using HIGH, you may need to add a splash of broth to keep it moist.

4. Can I make this recipe ahead of time, and how should I store it?
Yes! Cook the fajitas in the morning, cover with foil, and refrigerate for up to 4 days. To reheat, transfer to the slow cooker with 1–2 cups water or broth, cover, and cook on LOW for 1–2 hours or HIGH for 30–45 minutes. Avoid freezing as it can make the chicken tough.

5. What substitutions can I make for the slow cooker version if I don’t have one?
