Dates, Hazelnuts(best from a tree), Peanut-Butter(ingredients:peanuts), no sugar or artificial sweeteners, fat-filled yoghurt, cheeses, eggs, goat milk/cream (unpasteurized is best), brassica greens(better picked fresh), avocado, quinoa, rose-hip leather(better homeless-made), pure maple syrup, bacon if there is a stove.
The effect of canned goods is usually not good, and they are often all that is offered at food banks/soup kitchens, but beans sure, and sardines hell yeah!
Some people eat what keeps them healthy, no matter where they sleep or what they own.
Storage and ease of transport are often important considerations when there is a long hike to the rest/sleep spot or long intervals between food collection times.
Unlocked dumpsters, wild edibles and veggie-garden space with a water source are fantastic. If you have a piece of land where someone could put a tent/tarp; brambles one could remove to make growing space; a sheltered garage; a porch; a spot behind your garbage cans or under the stairs at the side of the house where someone could leave a waterproof bag with food and a blanket during the day…get to know your local homeless because many are really good, trustworthy people and you might be able to help enormously in a way you wouldn’t normally think of.
And please be careful with assumptions and unneccessary connotations in your communications, as they are cumulative and quite confusing in the long run.
Not to say this happened here, but as insignificant as it appears, adding ‘has-minimal-resources’ onto the already ambiguous and negatively loaded word ‘homeless’ is harmful.
