Spinach croquettes with walnuts and cheese

Ignore the quantities of milk and flour, I always make the béchamel sauce by eye! Poach the onion with a little extra virgin olive oil.

When the onion is golden brown, add the spinach and cook.

Once the spinach is cooked, add salt, pepper, crushed walnuts and feta cheese in small pieces. Cook for a few minutes.

Add oat flour and cook the flour a little, add milk until you have a bechamel sauce of everything (I have not added the quantities because I always do this by eye). Add a little nutmeg.

Let the dough rest in the refrigerator for a couple of hours to be able to handle them better. Once cold, coat in egg and oatmeal, and bake!
