I am still a novice to this technique, but a use for surplus eggs that helps reduce waste would be making pickled eggs.
Some pickled eggs recipes can be as simple as topping a container filled with peeled boiled eggs with vinegar and a little bit of salt to all sorts of odd combinations.
I'd recommend looking for an established recipe and start tweaking from there.
If someone had a recipe to provide, I'd be forever indebted.
