Hi. I've just put a pizza in for tea for dd. I noticed it said dont cook from frozen (that always confuses me as most pizzas are cook from frozen 
. So I took it out of freezer to thaw on the side for a few hrs. Have just noticed it says defrost overnight in fridge. Will it be ok? I put it back in fridge for a few hrs after I felt it was near thawed...the box still felt chilled
