We're going camping at a festival in a few weeks. My friend is talking about making food in advance (for her and her family), freezing it and bringing it along in a coolbox and it lasting the whole weekend (four nights) - cooking the meals on the gas hob each evening. I'd like to do the same if I can but I've been camping before but I haven't done this meal prep in this way before before...is my friend right? Will frozen meals in the coolbox last the whole long weekend? Is it safe? What do I need to add to the coolbox to keep things cool?
We won't have access to electricity. I know food will be available at the festival but I can't afford to buy it for every meal and would really like to prep in advance in this way but just want a bit of extra reassurance / advice on how to do this safely!
Would love any advice about coolbox / frozen prepped meals for camping then cooking them on the hob.
