Is it possible to put the smaller pieces of meat on a tray and freeze overnight, as you do vegetables or fruit......then in the morning, when hard, put them all together in ONE plastic bag, but since they were frozen individually, you're able to open the bag and take out what you want because they aren't stuck together? When you see the bags of frozen chicken in Trader Joe's, that's how they are, all frozen individually, then packaged together in one bag.

I've never tried very little meat to begin with, but can't see why it wouldn't work. You only need to put the pieces in the freezer long enough for them to get hard. I have done it with pieces of fruit or with veggies all the time. Just an idea.
