Add the chicken to the slow cooker. Sprinkle over the salt, pepper, garlic powder, thyme and oregano. Add the red onion, mushrooms and bacon. Pour over the pasta sauce.
Cover and cook on HIGH for 4 hours.
After the cooking time is done, shred the chicken with two forks. Sprinkle over the parmesan cheese and sliced spinach. Add the cooked and drained pasta. Stir everything until it is combined.
Add more parmesan cheese to the top and serve!

Notes
If you're looking for a healthier option or need a bacon substitute, you can try using turkey bacon or vegan bacon alternatives. Alternatively, you can omit the bacon altogether.
While the recipe suggests bow tie pasta, feel free to experiment with other shapes like penne pasta, fusilli, or rotini. Different pasta varieties can bring unique textures and hold onto the delicious sauce in their own way.
