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.

I made this last week, and it rivals fajitas in good Mexican restaurants. We use Mission low carb soft tortillas to save on the carbs and calories (I do not have any financial interest in Mission products).
