We like fritattas when we have a surplus of eggs but of course this doesn't address your BOILED egg issue.
I boil a dozen eggs every week and keep them in a container in the fridge, where my DH snags one every mirning to go with his breakfast of cereal and a banana. (He was a long -time bachelor and does not expect a cooked breakfast, lol!)
I like a sliced boiled egg on a fresh garden salad ...
A chopped boiled egg heated in cream of mushroom soup, served over toasted bread, makes a lovely warm lunch.
When I make egg salad, I boil a dozen eggs, there are four of us. And I serve it on split croissants, not sandwich bread!
