Work lunches no fridge?

[SC10]

We aren't allowed to use the communal fridge at work now so can anyone suggest lunches to take that would be nice when not refrigerated for a few hours?

I took some buttered malt loaf yesterday but like my butter to be 'cold/hard' in a sandwich etc and by lunchtime the butter had gone quite runny, so don't want to take Marmite/peanut butter sandwiches now which I had thought of doing as they would have been safe to eat after being out of the fridge for a few hours.

Get an insulated lunch box and pop a small ice pack in it.

What about taking your food in an insulated lunch bag with a small ice pack? Should stay at fridge temp for a couple of hours.

Make your sandwiches in advance and freeze them. They will defrost at work but the butter will still be cold.

I think most things would be safe, but if you prefer them cold you need a cold pack in an insulated lunchbox.

Would a salad be ok for you at room temperature? I used to do a nice panzanella or a couscous salad.

Thank you so much for all your suggestions, I really appreciate it.

Thermos flask with soup/pasta?

Same here! I take leftovers to zap in microwave

We are not allowed to use the microwave either now, the staff room is completely closed.

Thank you everyone for your great suggestions, I am looking online now for a small insulated bag to fit inside my work bag for commuting, and will also buy a thermos to take soup in Winter.

I was also going to suggest a small insulated lunch bag.

Should keep your stuff cool enough for a few hours.

Thank you Wheytaminute.
