Get out a slow cooker. Line the bottom of the slow cooker with celery. Season pork loin with Italian seasoning, garlic powder, salt, & pepper. Set pork loin on top of celery. Rough chop half an onion and toss on top of slow cooker. If available use probe to cook pork to 160F
Once the pork is cooked set a pan to boil your pasta (according to package instructions). Heat pasta sauce ( yeah if would probably be better if you made sauce from scratch but this is an easy meal). Once pasta is done and drained combine with sauce. Slice 1/4” pieces of pork. Plate spaghetti and pork. Sprinkle Parmesan over food. (If you are doing dairy free skip the cheese).
Soften cream cheese (either set on counter to warm up or put cream cheese in microwave on 10 second bursts until soft).
Mix cream cheese, pumpkin pie spice, & sugar. Mix on medium until incorporated and fluffy. Stir in pumpkin and eggs. Pour into crust and bake in over at 350F for 40 min.
