These chicken fajitas are full of flavor. You get smokey from the cumin and bold from the chili powder, similar to taco seasoning! There’s no real kick even though there are tomatoes with green chiles in there, too. I like to add spicy toppings to take it up a notch. This way, since my kids like to keep theirs mild, we can all enjoy this meal.
