to ask whether it's possible to cut a frozen pizza in half?

[Sullabylullaby]

I only eat half, and it's such a waste cooking a whole one.

I regularly do this with frozen pizza, hold the pizza in 2 hands and bash it on the work surface where I want it to break. Works every time. Cook half and put the other half back in freezer.

Cleaver and a rolling pin.

Sounds a bit sexy actually

Yup. Biggest knife. Score than cut hard.

Snap it using the edge of a counter top. Works every time.

Cut it when you've just got home from the shops, as it will be slightly defrosted then

I buy the perforated ones
