I don't let mine get too big that they are seedy. If one gets missed a couple times while picking I toss it to the chickens. They love them too.I like cukes just sliced into vinegar and a little pepper and water, plain with salt and pepper, cuke salad, dipped in ranch dressing, as a relish or just about any way I can get them
I do usually seed them out and peel them if the skins are tuff or thick
