In a large soup pot heat oil add onions, celery, carrot, potato and saute for 5 minutes add garlic, oregano, bay leaf, salt, pepper and turkey wings. Add peas and cover with enough water to completely submerge all ingredients by a couple inches.
Bring to a boil. Reduce heat and simmer for about 3-4 hours, until thickened be sure to stir throughout the cooking. The longer you cook it the thicker it gets.
Blend all but meat in a blender to smooth out, then shred the turkey and add to the soup.
