In bowl, mix together all the ingredients for the patties. If the mixture is too dry, add a tablespoon or two of Dijon mustard. Alternatively, if it is too wet/loose, add a tablespoon or two of panko.
Form a golf ball size amount of tuna in your hand, then flatten it out. Add a chunk of the cheese to the palm of your hand, then cover it with another golf ball size amount of tuna. Repeat.
Place the patties in the fridge for at least 1 hour in order to become more firm before cooking.
Set oven to 410F.
Spray a (nonstick) skillet with olive oil and set on medium heat. Then, right before adding the patties to the warmed skillet, lightly coat them one last time in the “crust” panko.
Sear the patty on one side for about 2 minutes or until golden brown, careful to ensure the patty is not sticking. If it is, then reduce the heat and/or spray the skillet with more olive oil. Then flip them over and place the entire skillet in the oven for 10 minutes.
Serve and enjoy immediately with a salad or on a multigrain bun. Note: as the patties cool, they become more solid and are less delicate; however, you don’t get the crazy, stringy, cheesy goodness either…just want to point that out. Lol
