Chop the onion and turkey breast into pieces.

Sauté them, and when they start to soften, add the spinach.

Transfer the sautéed mixture to a blender and blend everything together.

Add 1 tablespoon of flour and a splash of soy milk.

Stir everything until it forms a thick, pasty dough.

Once the mixture is cold, shape it into croquettes and fry them.
