Heat the avocado oil in a large pot over medium-high heat. Once hot, add the onion, garlic, carrots & celery. Saute until the onions are translucent, around 5 minutes, stirring occasionally.
Add Italian seasoning, garlic powder, cayenne pepper and cook for 30 seconds.
Add broth and bring to a boil. Lower the heat to simmer allowing the veggies to become tender, about 10 -15 minutes.
Add the tortellini and cook according to the package directions. I usually leave it in for about 2-3 minutes and then add in spinach or kale.
Remove from heat, serve & enjoy!
