I always eat toast with my bacon and eggs every morning. I put leftover buns in the toaster oven for a while and pour melted butter on them for my morning toast.
I do the same. Toasted leftover hamburger or hot dog buns are just fine for me with my morning eggs. Even if you don’t have a toaster oven, they fit in the toaster slot too - since most made in the last 20 years are wide enough to handle a sliced bagel.
It’s amazing that bread in a slightly different shape can puzzle so many people.
