1: In a pot, pour in the oil and the chopped celery, carrot, and onion. Sauté for 2-3 minutes.
2: Add in the chopped mushrooms and garlic, and sauté until fragrant.
3: Add the ground chicken to the pot and break up the lumps while mixing. Cook on high heat to dry out the water.
4: Once the water has dried up, add the spices and sauté for a few minutes.
5: Add the jar of marinara sauce and turn off the flame. Stir in spinach and cilantro, then set aside.
6: For the white sauce, in a saucepan over medium-high heat, melt butter and whisk in flour until it lightly changes color (about 4 minutes).
7: Gradually add warm milk and cream while continuing to whisk. Adjust seasoning to taste and thicken to your desired consistency.
