Blanch in boiling water for 2 or 3 minutes. Drain and place in ice water. Portion into sandwich bags and use a straw to suck out the air. Tie the bag without letting air back in (the best you can!). This lessens freezer burn and sogginess caused by excess air around frozen items.
Grate and leave in a colander for 30 minutes to dry out a bit, then portion into bags and freeze as above. You can add this to frittatas, tortillas or pasta sauces.
