To make the broth, combine the ingredients in a high-speed blender. Blend until fully combined. Strain through a fine-mesh strainer and set aside.
Using a dutch oven, heat the avocado oil over medium heat. Add the shell pasta and cook for 3-4 minutes, stirring often until crispy. Set aside.
Add the celery, carrots, and onion to the pot and saute for 4-5 minutes, or until lightly tender.
Add the ground beef to the pot and season with salt, pepper, cumin and oregano. Crumble the ground beef until browned and discard some of the excess fat.
Pour the broth into the pot along with the pasta and zucchini. Stir to combine and bring to a boil. Reduce to a low simmer and cover the pot, tilting the lid, for 8-10 minutes or until the pasta is cooked.
Serve topped with lime juice, avocado and cilantro.
