There was a segment on Sunrise last week with a lady and her book abuot freezing everything. There was a website but the name eludes me atm....sorry!

I personally do not like rice that is frozen just on its on. I only like it if the rice is coated in a sauce, or in a casserole iykwim? same with pasta

Potatoes shouldnt be frozen apparently, but the occasional few in a stew is ok.

Par boiling is great for vegies. If you over cook them, then freeze them, they turn to mush!
