This fajita chicken and veggies sheet pan recipe is delicious over a salad or rice – even wrapped in lettuce leaves. Leftovers are even better the next day because the lemony, balsamic flavors have additional time to blend with the bold taco spices. So be sure to make extra! And a little note to my veggie lovers – be sure and try the roasted celery and radishes. They are especially delicious when roasted in this taco seasoning, lemon juice and balsamic vinegar marinade.
