Set Instant Pot to saute mode. Add oil, onions, salt, pepper, crushed red pepper, Italian seasoning, oregano, and garlic. Saute until onions have cooked down (a few minutes).
Add in sausage and saute until mostly browned.
Add in broth and chopped potatoes and give it a good stir.
Cancel saute mode on Instant Pot. Set it to pressure cook mode on high for 10 minutes. Set valve to sealing.
Once done pressure cooking, set valve to venting. Let steam release fully. Remove lid, and add in coconut milk, greens, and lemon juice.
Stir everything well. Taste and adjust seasonings (especially black pepper, crushed red pepper, and salt).
Turn on the “sauté” mode. Let everything come to a boil for 10-15 minutes. Stir frequently to prevent burning. This helps remove the coconut flavor from the coconut milk.
Then, let everything sit for about 30 more minutes on the “Keep warm” mode on Instant Pot. This allows the flavors to really combine.
Serve hot, garnish with fresh parsley and/or parmesan cheese (optional), and eat with some crusty gluten-free or regular bread. Enjoy!
