Mostly, the thread seems to be about flavoring ingredients, and not strictly spices.
Garlic, thyme, rosemary, sage, Bell's seasoning, while meant for turkey, is good on chicken and tuna salad too, parsley counter-acts garlic breath, celery seed (healthier than celery salt), bay leaves, paprika, smoked paprika, dill (dill & garlic mixed into equal parts mayo and sour cream, with maybe a little sherry makes a killer sauce for cold salmon or a salad dressing--only takes a little) black Tellicherry pepper.

I can probably think of more, but I'm hungry.
