Tuna Niçoise Burger

This recipe for Tuna Niçoise Burger brings you all of the elements found in a Niçoise Salad, in burger form. You really won’t believe how delicious this burger is; it’s this month’s recipe for Fish Friday Foodies’ theme of Fish Burgers.

Fresh ground tuna, Niçoise olives, hard cooked eggs, green onions, lemon juice, salt and pepper are combined for the burger; when served on a bed of lettuce, tomato and slices of hard-cooked eggs, you’ve got a Niçoise salad on a bun!

My original plan for this month’s Fish Friday Foodies post was for this tuna burger, and I hoped to have the recipe made and my photo shoot done before I left for a trip to Seattle last week. I didn’t get it done, and now I’m so happy I didn’t.

While I was on my trip, I had oysters at the Shelburne Inn in Seaview, a small town located on the Long Beach peninsula on the Washington coast. The Shelburne Inn is a true American classic boutique hotel and the oldest continuously operating hotel in Washington.

The oysters I had were delicious, and topped with a caper and grain mustard aioli. I loved it so much that I thought it would be a perfect accent for this Tuna Niçoise burger. I’ve included a quick (cheat) recipe for the aioli, using mayonnaise as the base. You really need to mix some up when you make these burgers.

Mr. Saucy gives them two thumbs up…he was very surprised how much he loved them. Give ’em a try! And, check out all the other posts for Fish Burgers by my fellow Fish Friday Foodies in the links below.

I started cooking when I was ten years old. For me, the process of cooking, from inception of a dish, to the execution, to the washing of the pots is sheer delight. I am now retired from a business I still own, in partnership with my husband. I used to work six days a week and still cook every night. Now, I'm gardening, still cooking, always having fun and hoping to share my joy with you. Thank you for reading...and commenting! P~
