Step 1

Add the tuna to a large bowl. Stir in the onions and fresh parsley.

Step 2

In a smaller bowl, whisk together the egg, mayonnaise, Sriracha, lemon zest, and lemon juice.

Step 3

Add the liquid mixture to the tuna mixture and stir together. Add the bread crumbs, and use your hands to combine and mix evenly.

Step 4

Divide the mixture into 4 equal portions, about 1/2 cup each. Shape into 4 patties, each about 1 inch thick.

Step 5

Heat the avocado oil (or your desired cooking oil) over medium heat. Using a fish turner, gently lay the tuna patties in the pan, and cook until browned, about 3-4 minutes on each side. Season with additional salt and pepper, as desired. Serve warm.
