I prefer to use green onion including a bit of the green part for color. It's milder than red onion. Personally, I don't add mustard at all. Albacore tuna has such a mild taste I think mustard overwhelms the flavor of the tuna. And always Hellman's mayonnaise. I rarely add celery because it "weeps" into the tuna salad especially if you have any left-over.
Yum! I used two eggs to one can of tuna and added some fresh, diced, seeded tomato. The previous posters comment about powdered mustard threw me off and I used powdered mustard... I should have used prepared! All I could taste was mustard, and I had to double everything to make it better. Totally my fault, but for anyone else... 1-2 tablespoons means prepared mustard!
Simple, but flavorful way to make both plain "tuna salad" as well as this combo. I always add mustard (powdered preferably) to my tuna and it turns out with that added depth that lacks from just tuna w/ mayo and black pepper. This will become my new standard way of making these!
Exactly how I like my tuna salad. I must have eggs and onions in it. I really loved the mustard in your recipe. I used a little over 1 tbsp, but not quite the 2 tbsps. The celery seed seems like a lot, but it really isn't. Thanx for a tasty tuna salad!
