These steak fajitas have totally overtaken Taco Tuesdays in my house. My son with type 1 diabetes loves them, and I love giving them to him, because the entire recipe is pretty healthy and relatively low-carb. And it’s one meal that actually fills him up — an increasingly difficult feat for this growing preteen — without having to add a bunch of side dishes.

Another thing I love about fajitas is that they’re so customizable. We make a very basic meat mixture, which contains the perfect amount of spice for the kids’ palates, and then we can spice up the adult portions by adding a salsa with more heat. Serve the fajitas with your favorite tortillas or as a fajita bowl over a bed of shredded lettuce.
