Depends on what meat you use I have cooked with frozen foods as long as it's something that the meat gets chopped finely for and on a very low heat till it dethaws. Probably not the best but I'm not dead yet!

Otherwise dethaw in the fridge the previous day, I usually leave the meat wrapped up on a plate I've never had spillage

I think you can keep red meat for about 2-3months in the freezer? Not sure it should say somewhere on it. I know fish goes off really quickly as the enzymes that break down meat keep working at very low temperatures especially fish that live in deep cold water so I wouldn't store fish for long at all
