We are going to have the PIL over for a few days before Xmas as we have to work, so they will be providing childcare. Our fridge will probably stiffed full for Xmas day and cooking in the evenings would be a bit of a rush. We have a spare freezer, so I'd like to make some meals in advance and chuck them in the oven.
Where can I get foil containers for things like lasagne for 6 people?
