Depending on her reasons, you may not have to rule out all meats. Cooked bacon will (in my experience) store at room temperature for 6 weeks & I do mine "al dente" and can fry further in the field if desired.
Break it up & throw some in a package of 7 minute wild rice of something like Knorr side dishes and you're good to go. Lightweight too.
Around here, Dollar Generals are popping up like dandelions and they carry small bags of Clover Valley real bacon bits. I'll sprinkle 1/3 - 1/2 a bag in the water that I'm boiling for Idahoan instant potatoes & mix as per directions. Everything is better with bacon.
(note: In both above scenarios, I usually add
subway menu with prices it to the boil so maybe that kills bacteria. I just Googled this and found a bunch of websites that claim you cannot leave bacon unrefrigerated for more than 2 hours. Now, I've been doing it for years so I think they're being overly cautious but you'll want to stay within your comfort zone)
