Healthy way to use/eat cottage cheese? Do cheeses freeze well? Anyone pls?

1. For the first time, I bought and tried cottage cheese (5.5% fat) and am just wondering what else i can do with it aside putting in my salads. I liked it.

2. Also, I have this low fat feta cheese( my 3rd or 4th time of purchase), I've opened it but not finished yet and I don't want to throw it away 'cos i'll be away for two wks. Can i freeze it? or its just fine in the fridge for 2 wks?

Edit:

Sorry all! I mistakenly posted my topic in a wrong forum. If you're interest in answering pls check the healthy cooking methods forum. Thanks!
