Combine all ingredients except avocado oil in a large bowl. Let the mixture sit for five minutes to allow the oat flour time to absorb excess liquid. The batter will be slightly runnier than you would expect for a burger recipe, but that's okay!
2 cans tuna (7-ounces each, drained), 2 tablespoons avocado oil mayo, 2 tablespoons greek yogurt, ½ cup oat flour , 2 eggs, ¼ teaspoon salt, ¼ teaspoon pepper, ¼ cup green onions, ¼ cup parsley , 2 tablespoons dijon mustard
Preheat a large non-stick skillet on medium-high with avocado oil in it. Using a ½ cup measuring cup, add batter into the skillet and spread out to form 4-5 patties. The batter will make four to five patties, as shown in the process photos above.
2 tablespoons avocado oil
Cook for 4-5 minutes on each side until golden brown and fully set in the center. Serve immediately or save for up to 3 days.

Notes
I used two Costco size 7-ounce cans of tuna. If you don't have the giant cans from Costco, you can use 3 regular-sized (5-ounce) cans of tuna instead.
