I eat a 5lbs bag of frozen chicken tits every week and have to make them tolerable to reheat without drying out. Like i said earlier, i beat my meat. Get it all a uniform thickness so none of it is over or undercooked. Best thing in the world is brining it to make it nice and moist.I toss a few tablespoons of salt in the bottom of a big ass stainless mixing bowl and fill it half way with hot water to dissolve the salt, add 4ish frozen chicken tits, cover with plastic and put it in the fridge before i leave to work. It really holds the moisture in the chicken after cooking. If I buy fresh chicken, 30-60min is enough time sitting in the brine. I've also found the perfect time and temp combo in my particular oven to get it just right. 350 for exactly 32min gets the internal temp 158-160* every time.
Other than that, no "tricks".
I got some Flavor God seasonings for xmas, and they're amazing. WELL worth the cost.
