I am currently walking/biking 4 miles to work, which means carrying my lunch in my back pack. I'm also eating gluten free (by necessity due to a gluten sensitivity), and also trying to avoid processed foods (or at least those with extra ingredients like preservatives) and added sugar (including added sweeteners like honey, cane sugar, coconut sugar, etc). I recently started baking my own GF sandwich bread, but will not be doing that for long -- I found a good recipe that I can leave the sugar out of, but it uses a rice flour mix, and I want to keep my rice intake down due to all the arsenic info that's out there these days. Other all-purpose flour blends that I've come across are prohibitively expensive - so once I run out of the blend I have now that's mostly rice-based, GF bread will be out as well.
I'm also currently pretty tight on free time, so I've stopped cooking dinner most nights. Until recently, lunch was always leftover dinner. But there are now two issues with that - (1) not having time to cook dinner and do dishes, and (2) worrying that leftovers in a container may leak in my back pack.
So, I'm looking for on-the-go ideas (to the extent that it needs to be backpack friendly without risk of leaking, and relatively easy / quick to prep) that fit my other restrictions. Currently all I can come up with is a salad in a jar (spinach, veggies, seeds/nuts, maybe some cheese, or leftover taco meat since we are going to do tacos once a week for dinner - I have oil at my office and can add that as the "dressing" at lunch time), maybe peanut butter and banana sandwiches on corn tortillas, and potentially something like nuts and fruit/veggies, which I'm afraid might not fill me up enough.
Any suggestions would be greatly appreciated :)
