Now I know it's a phaf...and possibly not something you're prepared to knock up for mid-week quick tea. However if you make a quantity, and it really only takes a few minutes, in advance and leave it in your herbs/spices drawer it comes in very handy, not only for fajitas but as a marinade(add olive oil)/rub for fish and meats. As for whether it's better than shop bought fajita seasoning, I think so it really does taste more authentic and smoky with the added benefit you know exactly what's in it.
