My Very Best Steak or Chicken Fajitas

READY IN: 3hrs 5mins
Recipe by HeidiSue

We've tried several fajita recipes & finally this is it! I found this recipe online and have tweaked it to our liking. Make it with beef or chicken. Great for having a fajita party!! Prep time includes minimum marinating time.

Ugh. I didn't make this. I didn't get past the first ingredient. I'm trying to MAKE a fajita marinade. When it starts out with "McCormick fajita seasoning" I know it's not the recipe I'm looking for.
