Turn on the heat to medium high, add the oil and butter, add the onions, garlic, parsley, spring onions, the Brazilian seasoning blend and the bay leaf, to your pressure cooker and stir for 2 minutes. If the pressure cooker is electric, set to brown.
Add the remainder of the ingredients, stir to combine, close your pressurecooker. If manual, leave it for 4 minutes when pressure is on. If your pressure cooker is electric, set it to manula, high pressure, 4 minutes.
When the 4 minutes is passed, manually remove the pressure from your pot, and serve it with a tablespoon of mayonnaise, this step is optional but it makes the potatoes even better.
