In a food processor combine the aji, garlic, onion, and ¼ cup water and process to a paste. Remove to a bowl.

In the processor blend the walnuts, cracker crumbs, milk, oregano, and salt until smooth.

Heat the oil in a pan. Add the garlic and onion paste and stir-fry until golden over low heat. Add the turmeric and stir another minute. Add the broth, turkey (or chicken) strips, and Parmesan cheese and bring to a boil. Add the milk sauce and cook, stirring constantly over low heat for 5 minutes. It should be smooth and pourable. If too thick, add more broth until you have reached the desired consistency.
