Is it actual octopus, or is it squid Debih?
There's quite a difference; as far as I know, octopus is tough and needs careful cooking (bashing on rocks rings a bell!) but yes, google
Squid is lovely and once cleaned would freeze fine. It needs either very quick cooking - a minute or two - or else quite long cooking; in between it's chewy.
Nigel has some good recipes, or BBC good food probably
Cleaning etc is a bit of a faff but not too bad - get the instructions online and get Mick to do it
