Bechamel sauce for spinach and turkey croquettes

Sauté a large chopped onion (it is not necessary to chop it finely because everything is then crushed).

Add whatever you are going to put in them, ham, meat, fish ... (I have put frozen spinach and turkey). Stir to mix well with the onion without removing from the low heat.

Add three heaping tablespoons of flour and continue frying until the flour is well browned.

Add: Two glasses of milk (I used soy drink). One chopped garlic clove Parsley

Crush it

Add: pinch of salt, pepper and nutmeg. And now stir until it thickens and when you see that when you move it, it comes off the wall of the pan, it's done!

Put it in a flat dish and let it cool, then put it in the refrigerator and I make them the next day.
