Step 1. Heat olive oil in a large saucepan over medium heat. Add the wild rice and toast it, stirring occasionally, for about 2 minutes.
Add the onion, carrot, celery, salt, pepper, and poultry seasoning. Stir well to evenly distribute the seasoning. Cook for 5-7 minutes, or until the vegetables are tender, stirring occasionally. Add the garlic. Simmer for a minute.
Add the turkey stock to the pot and bring to a simmer. Let simmer for about 20-25 minutes, or until the wild rice is fully cooked. (It should be tender and chewy.)
About halfway through the 20 to 25-minute simmer, stir in the spinach.
Once the turkey has wilted down into the soup, reduce the heat to low and stir in the turkey. It’s already cooked, so you only want to leave it in over the low heat long enough for it to heat through.
Transfer to bowls and garnish with fresh parsley and chili flakes if you like a little heat.
