In a small pot or bowl, combine the chicken seasoning.
Use a knife to horizontally slice each breast right through the centre to create 4 even-sized cutlets. Evenly coat both sides of each cutlet with the seasoning.
Add the oil and butter to a large, deep saucepan over medium-high heat. Once hot, add the chicken and fry both sides for around 3 minutes, or until lightly charred with the chicken just about cooked through the centre. Remove from the pan and place on a plate to one side, leaving the excess fat in the pan. Slice the chicken into thin strips just before needed.
Lower the heat to medium, then add the garlic and fry for 10-20 seconds (be careful it doesn't burn). Stir in the tomato puree and fry for a minute, then pour in the wine. Simmer for a few minutes to reduce the wine until it is almost evaporated, with the pungent smell of alcohol gone.
At this point, you can add the pasta to salted boiling water and cook until al dente. Drain when needed, retaining a cup of the starchy pasta water.
Stir the stock and cream into the saucepan, then stir in the parmesan and seasonings until everything is blended. Bring to a simmer and cook the sauce for around 5-7 minutes until it thickens. Stir in the resting juices from the chicken, then season to taste with salt and pepper.
Stir in the drained pasta, thinning out with a splash of leftover pasta water if needed. Stir in the spinach until it begins to wilt, then stir in the chicken until everything is coated in the sauce. Again, thin out with a splash of pasta water if needed, just make sure the sauce thickens and clings to the pasta in the end.
Serve with extra parmesan if desired, then tuck in and enjoy!
