Have you ever heard of a Salmon Hash. Served over grits.

Thanks drbabs for your input. First, let me say, I am NOT a cook. I'm 76 yrs old and looking for something simple and easy. I'm not feeding an army, just me. You may be on the right track about a salad rather than a hash because this dish was served cold no cooking involved. I'm even considering, maybe, adding some boiled egg. Thanks again.

Also! If you leave out the eggs (not in the ingredients list but in the instructions) and don’t make patties and fry them, this is basically salmon hash. https://food52.com/recipes/85801-best-salmon-cakes-recipe

Did it have mayonnaise, too? It sounds almost like tuna salad made with canned salmon instead of canned tuna. Something that my Southern mother might have served with grits.

Or it could have been something like this that she just added vinegar to from this link:

Salmon Hash

(Serves 2)

2 medium red potatoes, cut into pieces
1 can salmon, drained and chunked
½ small onion, chopped
1 red pepper, sliced
2 eggs
Boil the potatoes until tender and drain. While potatoes are cooling, saute red peppers and onions until tender. Gently stir in potatoes and salmon; set aside and keep warm.

Poach or fry eggs (over-easy method). Divide salmon-potato-pepper mixture on two plates and top each with an egg. Salt to taste.

Yes, but a long time ago. Can't find single recipe for salmon hash and grits, but these two recipes (one for salmon on grits, from Athens, Georgia; one from a fish market in Ann Arbor for a salmon hash) should help you reconstruct the dish.
Hope it works! Please let us know what you eventually cook and how it turns out..:)
