Select the "Saute" function on the pressure cooker.
Add the olive oil and brown the sausage.
Add the onion a few minutes before the sausage finishes browning to soften.
When the sausage is browned, turn off the "Saute" function.
Add the potatoes, kale, broth and seasonings. Do not add the almond or cashew milk yet.
Lock the pressure cooker's lid in place and select the "Soup" function. I used the 30 minute function.
After the cooking is complete, either wait for pressure to naturally release or CAREFULLY do a manual release. Soups spray and spatter if you immediately try to release the pressure, so I recommend waiting at least ten minutes if you are going to manually release the pressure.
Add the almond/cashew milk and stir. The soup should be hot enough to heat the milk addition without additional cooking.
