When the avocado oil is fragrant, add butternut squash. Sauté for 5 minutes, stirring frequently. Add yellow onion and cook for an additional 5 minutes.
Add in turkey sausage, garlic, and thyme and let cook for 1-2 minutes.
Finally, add spinach and let it cook down for about 3-5 minutes.
Create four divets in your squash hash with a spoon and crack an egg in each divet. If you would like to bake the eggs, cook for around 15-20 minutes at 350ºF. If you would like to fry your eggs, turn heat down to low/medium, cover pan and let cook for 7-10 minutes.
Remove from heat and season with salt and pepper to taste.
