Maybe it depends on climate, but bread left out where I am gets moldy way before it gets stale. The best solution is to keep it in the freezer (in a bag, and any of those methods but CE would probably be fine). Weeks later, the bread is still soft and send fresh. Bread thaws unbelievably fast. If I’m making a sandwich, I take two slices out and put them on a plate separated. Usually by the time I’ve got the other ingredients ready to go, the bread is thawed. If you’re toasting the bread, it can go straight from freezer to toaster. If you’re making sandwiches to take to work or school, you can just make them on the frozen bread.
