I'm even simpler. Go grab some "Chicken rub" from the grocery store - last one I got was mesquite kick or something. Also, marinating helps. I use the soyaki sauce from Trader Joes or green salsa.
I'm always a fan of MyProtein - there's always some 30%+ discount, so you can get good deals, and their quality is top notch. It comes in a bag so you know they're trying to keep it cheaper than the competition.

When they changed it to the Gen4 version, I noticed that it didn't hit quite as hard as the original. I might give some of the other variations a shot.
