In a large stock pot, heat the ghee over medium-high heat. Cook the garlic and onion until soft. Add in the beef and season with the cumin through the paprika, breaking up with a spoon while it cooks. Once the meat is cooked through, drain any excess grease and remove half of meat and store it in an airtight container in the fridge for the following day (Quick and Easy Tacos).
Add in kale and celery, sauté for another 1 to 2 minutes, then add in bone broth and lime juice.
Bring the mixture to a boil and then reduce heat to low, cover with a lid and continue to simmer for another 30 minutes.
After the 30 minutes, remove soup from heat, serve and top with cilantro and avocado.
