I. LOVE. FAJITAS. Because they are easy and tasty and I most always have all of the ingredients at the ready! My favorite fajitas are usually made this way with sirloin steak, BUT HEAR ME OUT. You can make amazing fajitas with lesser cuts of beef, including BEEF STEW. Trust me. Watch to see how I made these and feel free to sub roasted vegetables or other meat (like chicken, if that’s your thing. No judging here. ).
