In a mixing bowl, combine the oatmeal and milk. Let it sit for 5–10 minutes to allow the oats to soften and absorb the liquid.
Add the eggs to the mixture and whisk until you have a smooth, thick batter.
Stir in the chopped green onions, shredded mozzarella, salt, chili flakes, and Provençal herbs. Mix well to distribute the flavors evenly.
Heat a non-stick skillet or pan over medium heat. Add a drizzle of oil.
Pour a scoop of the batter onto the pan and gently spread it out into a round pancake shape.
Cook for 2–3 minutes on each side, or until golden brown and fully cooked through.
Transfer to a plate, garnish with sesame seeds and a sprinkle of extra herbs or green onions if desired.
Serve hot with your favorite dipping sauce or enjoy on its own!
