you can make mayonaise, and then a bunch of different flavored mayonaeses, then you can hardboil the rest, and split those into seperate meals.
hardboiled egg as is, hardboiled egg on a salad, hard boiled egg on a sandwhich, devil'd eggs, ect. and as other anons said, use them in baked goods. cakes, cookies, pancakes, breads, ect.
and obviously you can just do regular breakfast eggs: scrambled, fried, sunny side up/down, ect. I think people also make tarts and various kinds of puddings with eggs but i have no experience with that.
