Mirch bhai,
I usually slice the chicken breast horizontally and then marinate it with lemon, my ammi's all purpose masala :) and salt. And then I make individual servings and wrap in cling film and then they go into freezer bags. So I think they do have quite a bit of marination, the masalas are in there pretty good (they taste real good thats why and they are juicy) just this lil prob of threads getting stuck in my teeth.
