Did your Costco restock them? Our Van Isle Canadian Costco always does; between our 4x4 and motorcycle travels, and this year we've put in well over 30 hiking days due to the crazy vid; we have our hashbrowns most mornings. The hashbrowns crisped in bacon fat, then we had pre-made eggs n veggies, sausage and the bacon, sometimes cheese.
Pictured is my luxury item on last weekends trip to a remote beach, I carry wood burning camp stove and a bag of charcoal. Burns a long time, can simmer up the hashbrowns and still keep the coffee hot. In remote areas I've made bbq'ed hamburgers in rainy conditions travelling on motorcycle. I was on the KLR this trip, and luckly found a vacant covered area with firewood for 2 nights.
