Mm how long will the food have to hang around for before its cooked? Any chance of getting a cool box and preparing your stuff beforehand then just getting it out? The first day is easy as anything'll last til the night time without a cool bag but day 2 is trickier.
If you're having a BBQ:
Chicken is free and easy, you could rub some Schwartz spices in to make it tasty. (Maybe even chop it up and skewer it on kebab sticks, depending on if you'll have the time/energy/desire). Otherwise low-syn sausages. Take a bag of salad you can just open and eat with it. In fact take two, it'll last at least one day in the shade.
Personally I would not bother with the burger bun, it won't stop at one bun and they're more than a HEX each, better to have more chicken/low fat sausage/salad-y stuff. Avoid or go minimal on cheese/ketchup etc.
If you're not having a BBQ:
Tins of beans, Batchelors savoury rice thingies, pasta, sachets you can just bung water in like Ainsley Harriot couscous. (In fact any cous cous/bulgur wheat - you just pour water on, leave it xyz minutes then chuck any kind of spicy seasoning mix on and voila. I use the Schwartz Cajun jar a lot)
Also take loads of fruit, plus carrots and/or mini veggies like sugar snap peas, baby sweetcorn to snack on and to fill meals up.
If there's no cooking going to happen at all then make up some hot food before you go and stick it in a flask or two, or even three and/or make some cold salads eg couscous/bulgur wheat/beans that can go in Tupperware boxes for a day or so. As long as it hasn't got meat or rice in it it should be fine for 24h or so. And obviously still take the fruit/carrots/mini veggies etc.
There also used to be a few tins of stuff like curry you could get that were free/low syns but I dont know if they still are as I havent eaten that kind of stuff in a while.
have a good w/e! x
