Hi! I've recently decided I should start packing a lunch for work rather than eating out, in order to improve my health. Unfortunately, I'm struggling to think of stuff to pack. I'd love to hear your suggestions!

Some things to consider: - I don't have access to a microwave or other appliances to heat food. - I'm weird about eating warm foods cold. For example, pizza, soup, or other leftovers are repulsive if not reheated, but I can eat cooked things cold like roasted veggies and some pasta salads. I'll take all suggestions, but my preference is food that's mostly raw or made cold to begin with. - I'm not very big on tofu, especially cold. If it's in something, it needs to be hidden. - I can't refrigerate my lunch. I don't mind eating room temperature food, but please don't suggest things that will spoil within 6 hours unrefrigerated. - I don't like most condiments (besides BBQ sauce) or any sauces with mayo in it. I'm not a fan or sandwiches either, but maybe some of you can suggest one that'll change my mind. - I can bring a thermos if needed, but I don't own one at the moment, so ideally something that doesn't require me to purchase one. - Not mandatory, but bonus points if it's high in protein and/or iron and if it'll keep me full for hours. I'm more of a snacker, but I can't snack during work, so I need something that'll keep me full for long. Also open to suggestions for breakfasts that'll keep me full till lunch!

Hopefully this isn't too restrictive, I'm open to hearing any and all suggestions, hopefully some will work for me! Thank you so much in advance!!
