Mmmmmm i love fajitas This is a flank steak fajita recipe that's straightforward to make and totally delicious. Flank steaks make for great fajita meat because they're thin steaks that easily slice. They also have deep beef flavor that's a perfect complement for fajita seasoning. Since the flank steak is a thinner steak, you want to be careful to not overcook the steak. We're providing instructions on how to grill the steak, but it's also perfectly fine to broil or pan fry the steak if you can't get outside to grill. If you have a great recipe for a fajita marinade or seasoning, share it in the comments section-we'd love to see it
