I will be doing a training / retreat next month where I have to bring my own food for lunch and snacks, in advance (meaning I arrive on the first day and need it all there with me ahead of time for the full seven days, no chance to go shopping during the training). This training is very physically demanding and my lunch will need to be foods that give me a sustained energy boost. I'm not sure but I don't think I'll have a microwave available and certainly not a stove or oven, but definitely a fridge and cabinet space. I need ideas that I can assemble easily, and perhaps also some pre-made stuff. Ideas I have so far:
hummus and raw veg for dipping
make wraps or sandwiches with cheese/ cottage cheese, veg, nori flakes, seeds and nuts
good old peanut butter and jelly
dried fruit / nuts/ trail mix
power bars ,etc
soup cups (we'll have a water boiler)
Any other ideas? I have a very fast metabolism and I would normally eat a huge, warm meal midday to keep me going....but unfortunately we only have warm meals for dinner during the retreat. I'm a bit worried I won't be able to eat a big enough lunch to really fill me up and keep me going. Also are there any teas or other drinks I could drink to this end (we can't use caffeine during the retreat though)?
ETA: I'm not sure if this would fare better in the meal planning and/or vegetarian forum, so mods feel free to move it.
