Savoury uses for tons of egg whites?

[TeddyIsaHe]

I have lots of egg whites to use up (10!) and need some savoury ideas that aren’t soufflés.

I have a total mind-blank!

Refilled baked potatoes: Beat the egg white and add to the potato middle and lovely cheese with whatever additions you like (onion, chopped bacon etc) . WHen it goes back in the oven it rises a little and is deliciously light.
You don't need the yolks for egg fried rice or Chinese egg drop soup.

We have used them in mash in place of butter.

I'm sure they a be frozen if you have too many.

I cannot remember where I saw the recipe, online somewhere, but you can make a savoury equivalent of sweet meringues with parmesan, to serve as canapés. I keep meaning to try it, but forgetting to buy parmesan.
