Our love for our cast-iron skillet runs deep. We make pizza in it. We make cookies in it. And now we make this chicken fajita recipe in it. But not on the stove top. Lets discuss: rather than sauting the ingredients, you simply place the chicken and vegetables into the skillet, toss them with taco seasoning and put the whole pan in the oven to roast. As its cooking away, you can prep the tortillas and all of your favorite fixings, like guacamole and salsa. When you remove the sizzling skillet from the oven, its dinnertime. (bonus: since this is a one-pan meal, cleanup is a breeze too. ).
