I agree Hungry. And the restaurant I cooked in...we simply cooked what we needed. VERY few things were frozen and nothing was prepared ahead of time like this. It seems like you may be saving time, but, you are actually compromising flavor instead.
Do you work in a restaurant or is this just for home use? If it's for home use I'd try browning smaller quantities at a time THEN freezing.
