Yes. I mashed the German potato salad with a fork. Then, with kitchen shears, cut the cooked cabbage into small pieces. I mixed in some Himalayan salt, bread crumbs, and an egg substitute (chickpea flour & ground flax seed mixed with water). If I'd had Swiss cheese I'd have added it. Then I cooked them in my air fryer. Surprisingly delicious with a nice texture. So easy. All in one bowl. Just used mayo and brown mustard on the sandwich with lettuce.
I just watched a cooking show episode where they explained George Washington helped the troops survive by getting help from Native American woman who taught them how to properly prepare corn so they wouldn't bloat and die from eating it incorrectly. When I was a kid, we were told he invented popcorn by mistake over a campfire.
