Roast the poblano peppers in a frying pan over high heat, until they are black on the outside. Add to a plastic bag, seal, and let sweat for 10 minutes. Remove from the bag and remove the skin and the seeds.
Cook the whole wheat spaghetti by package instructions. Drain - do not rinse - and set aside. Don’t forget to reserve 1 cup of the pasta water.
While the spaghetti is boiling, saute the onion, garlic, tomatoes, and spinach in a skillet for 5 minutes.
In a blender add the green peppers, sauteed vegetables, chicken stock, reserved pasta water, Greek yogurt, cumin, garlic powder, salt, and pepper. Blend until smooth.
Add the blended sauce to a pan and bring to a boil then lower heat to medium. Let simmer for 5 minutes. Add more salt and pepper to taste.
Add the cooked spaghetti to the sauce and mix well. Transfer to a baking dish or a cast iron pan, and top with mozzarella cheese. Bake or broil until the cheese is melted. Serve and enjoy.
