1. they do make shelf stable, individual hummus. it's not a cheap solution, but if you stock up on those before you go you could dip all veggies but the greens in it.
2. if you have any access to a fridge, bring a sauce a shift and use that. so one shift you might bring teriyaki and steam a stir fry with teriyaki sauce with the broc, caul, onions, peppers and chicken if you eat it. and that works if you bring teriyaki, hoisin, orange sauce, curry, essentially any jarred, somewhat liquid foodstuff. if you don't have access to a fridge, start playing with spices in your offtime. find blends that you like [rosemary and garlic for example] that you can bring in jars or ziploc baggies along with a small thing of olive oil and use that in place of the premade sauce to season.
2b. i'm not sure if you've ever heard of mary jane's outpost, but her camping thing is basically bring a bunch of oats and quinoa and then a variety of spice mixes [outlined in the book, there are cajun and curry and all sorts of different blends]. you cook the grain, add the mix and eat.
3. chicken or egg salad. if they don't have mayo, stock up on a few packets everytime you go out to eat or go to a wholesaler that sells them a buy a box of the packets.
4. i've never tried cooking down apples in the microwave to make applesauce, but if i were in your situation i would give it a go. it could go on raisin bread as a nice snack.
5. steamed veggies with cheese on them. again, bring and add spices if you'd like.
6. bread plus veggies of your choice plus cheese with or without chicken or egg is a nice sandwich
7. i like using mandarins in place of dressing on salads, especially spinach salad.
8. i don't know how much room you have or want to devote to bringing stuff [spices seem easily packable and therefore a given] but they do make:
- cup of soups. nile, health valley and dr macdougall's have some great options like black bean soup [13 g fiber in a cup!], chili, lentil curry, miso and potato leek to name a few. all you need is hot water
-thai kitchen noodle carts. again, you add water and heat.
-dehydrated fruits and veggies. just tomatoes is the most common brand here but they have peppers, carrots, blueberries, corn, peas, raspberries, apples and a ton of other things i can't remember at the moment
-individual nut butter packets
and bringing at least a few could be a break in the monotony
9. chop up veggies, mix in with cream cheese. you can spread it on your chicken, your bagel or plain pasta if you can get it.
-google first. ask questions later.
