Prep the ingredients: Drain tuna well and place in a large mixing bowl. Grate the onion, mince the garlic, and finely chop the parsley. Add to the bowl.
Prepare the oats: Add the oats to a food processor or a blender and blend into a coarse flour (about 1–2 minutes). Add to the bowl.
Combine the mixture: Season with salt, pepper, and chili flakes. In a small bowl, beat the eggs, then pour them into the tuna mixture. Mix everything until well combined. Let the mixture rest for 5–10 minutes to hydrate the oats.
Shape the patties: Using damp hands, form the mixture into 10 patties.
Cook (choose your method):
a. Pan-fry: Heat olive oil in a skillet over medium heat. Cook patties for 3–4 minutes per side, or until golden and crispy.
b. Bake: Preheat oven to 375°F (190°C). Place patties on a parchment-lined baking sheet. Lightly brush or spray with oil. Bake for 15–18 minutes, flipping halfway, until lightly golden.

Notes
Types of Oats: You can use rolled oats, quick oats, or oat flour. For the best texture, blend the oats briefly in a food processor. If you prefer a coarser bite, skip this step.
Cooking Methods:
Pan-frying gives a crispier edge and richer flavor.
Baking is lower in oil and great for batch cooking. Flip halfway for even browning.
Add-ins & Mix-ins: Feel free to mix in grated zucchini, carrot, or chopped spinach for extra nutrition. Other herb options include dill, cilantro, or chives.
Flavor Boosts: Add a squeeze of lemon, a spoonful of Dijon mustard, or a dash of smoked paprika for added depth.
Storage Tips: Store cooled patties in an airtight container in the fridge for up to 4 days or freeze for up to 2 months. Reheat in the oven or on a skillet for best texture.
