Use a large, deep pot to brown the ground beef and season with salt, pepper and oregano. Set aside, leaving about 2 tbsp of fat in the pot.
Add the onion and garlic and saute for 3-4 minutes or until lightly translucent.
Add the beef back to the pot and stir in the water, salsa, and pasta. Stir well to combine.
Turn the heat to high and bring to a boil. Reduce the heat, bringing the pot to a simmer. Allow to simmer for about 12-15 minutes, stirring often, until the pasta is cooked through and the sauce is reduced. See notes in the pasta needs more time to cook to your liking.
Stir in nutritional yeast to taste, lime juice, avocado (or reserve if saving for later), black olives, and green onion. Serve fresh.
Notes
To make this AIP, rather than using salsa, you can use this homemade AIP enchilada sauce. Of course, the flavor is different, but it's still a great swap to keep it nightshade-free.If the pasta needs more time to cook to your liking, add about 1/3 cup of water and simmer for 2-3 more minutes until the pasta reaches your desired doneness.All nutritional information are estimations and will vary.
