Best way to freeze homemade burgers?

[bytheMoonlight]

I have two left over which I may as well freeze instead of cooking and throwing.

But what should I wrap them in?

I flat, open freeze and then stick in freezer bags.

Freeze on greasproof/baking paper so they won't stick, then put them in a plastic bag when frozen.

Thanks I've wrapped in baking paper and will put in freezer bags later
