Drain the tuna and place it into a large bowl. Flake it with a fork to break it apart.
Add in your grated carrots, chopped spinach, scallions, eggs and spices and mix together well.
Fold in your oat flour and toss together until evenly incorporated.
Heat a large pan over medium heat, then drizzle in about 1 tbsp of olive oil.
Scoop out some tuna mixture to form palm sized patties, squeezing them tightly as you shape them so that they hold up well. Cook about 3 at a time on the pan on medium/low heat for about 5 minutes, flip and cook for additional 3-4 minutes.
Serve fresh with your favorite dipping sauce! Leftovers can be refrigerated for up to 4 days and reheated over low flame or in the oven.
