Mash 1 Banana in a bowl until mostly smooth. Add 1 Egg, 45 g Oats, 1 teaspoon Flax seeds, 0.5 teaspoon Ground cinnamon, and a pinch of salt (optional).
Mix until fully combined. Let the mixture sit for 2 to 3 minutes so the oats and flaxseeds can absorb some moisture.
Heat a non-stick frying pan over low to medium heat and lightly grease the pan. Pour the oat mixture into the pan and spread it into an even layer, like a thick pancake.
Cook for 4 minutes, or until the underside is set and golden and the top looks mostly firm. Carefully flip it over and cook for 2 minutes on the second side.
Use a spatula to break it up into rough pieces so it looks like a scramble.
Cook for 2 minutes more, stirring and turning the pieces so they dry slightly and cook through, forming small clusters.
Notes
Use a ripe banana. It gives better sweetness and helps the mixture bind.
If you prefer a smoother texture to scrambled oats, pulse the oats in a blender a few times before mixing.
Keep the heat moderate rather than high. If the heat is too high, the outside can brown too quickly before the middle sets enough to flip.
If the mixture feels too wet, add 1 extra tablespoon of oats. If it feels too thick, add 1 tablespoon of milk before pouring into the pan.
