aha now I am just about to load the car today for a 5 day festival trip (Big Green gathering anybody??)
so if it helps this is our meal plan & food list. we are vegetarian (plus tuna for dd)and have read on festival info that you can't go on and off site with your car, so no popping to supermarket to stock up.
also there will be presumably minimal facilities so nowhere to wash up.
5 main Meals:
day 1 (arrive) couscous salad & rice salad with veg sausages made at home & brought in cool box. Tomatoes, cucumber, etc.
day 2: stir-fry - ready chopped veg, straight-to-wok noodles, ready sauce, plus cashew nuts. For fussy DS - noodles cooked in egg plus tinned sweetcorn.
day 3: rest of eggs for breakfast. Pasta & ready sauce, tinned tuna, veg which cook quickly eg courgettes, baby corn, or tinned veg. Salad (if unopened should keep OK).
day 4: ready egg fried rice & tinned aduki beans & sauce & same veg.
day 5: baked beans!!
Plus; breakfast cereals, general snacks, flapjacks, pitta bread (keeps longer), peanut butter, marmite, malt loaf, biscuits, crisps, lots of dried fruit. Am trying instant porridge (just add hot water) for first time. I buy little individual cartons of (rice) milk & juice because can't keep opened ones fresh.
obviously there is more scope if you are camping next to your car, so can have a cool box there, or have EHU.
