In a large pot, boil enough water for pasta and cook according to package directions, reserving the cooking liquid when complete.
While water boils, add the filleted chicken breasts to a mixing bowl with 1 tablespoon olive oil and all spices except salt and pepper to chicken until each fillet is fully coated.
Heat a wide saucepan to medium heat and add 2 tablespoons olive oil. Add chicken and cook each side 2-4 minutes or until golden crust forms on each side. Set cooked chicken aside on a plate
In the same saucepan add diced onions and cook until translucent. Add in garlic, cook for 30 seconds or until fragrant and then add diced tomatoes with juices, scraping the brown bits from the bottom of the pan. Simmer for 5 minutes
Add in white wine and cook another 5 minutes. Add salt and pepper to taste
Add heavy cream and stir. Taste to see if more salt is needed, then thin out, one ladle full at a time, with cooked pasta water.
Add in spinach, let wilt – about 1 minute. Add cooked chicken back to pan and simmer for 2-3 minutes.
Plate your dish with pasta, chicken and sauce, garnish with shredded Parmesan, basil leaf and serve!
