@ossobuco,
Quote:I put them in salads, including tuna salad sandwiches. (I've started using more of certain vegetables and herbs

I like the idea of a tuna & celery greens sandwich, osso! Two good strong tastes together! Yum.
Or using them as a herb, though I'm not sure of what sorts of (cooked) dishes they'd suit.
In big bowl Vietnamese soups the finishing touch, right at the very end, is often to throw a big, generous pile of raw herbs - like mint, Vietnamese "mint", parsley, some chopped Asian greens ... etc, etc, on top. A very nice touch, I think! Perhaps a few celery leaves might go well here?
