Fajita Meat …Skirt, Flank & Flap! These three are the prime choice for delicious fajitas or carne asada! Flap Steak is the hidden gem here …it is from the same area as the flank steak but is thicker thus easier to cook with the same “grain” as skirt and flank. All three are fantastic depending on your preference! Cut across the grain for best results after cooking.
