Prep all your veggies (wash, peel, chop, mince etc...)
In a very large stockpot add avocado oil and onion, garlic, leeks, and celery. Sautee for 3-5 until the onions become a little translucent and a bit tender.
Add ground beef and cook until the beef is fully cooked.
Once the ground beef is cooked drain the excess fat. This is SUPER Important or you will have a large amount of oil floating on the top of the soup.
Place stockpot back on the stove on medium-high and add sweet potatoes, carrots, and squash. Next add the broth, tomato sauce, whole tomatoes, dried parsley, and dried oregano. Bring to a boil, then reduce heat to a simmer with the lid on. Let simmer for 25-30 minutes until veggies are fork-tender.
Notes
Can't find delicata squash? You can sub any other type of winter squash such as butternut or acorn.
