Heat the oil on low in an 8 qt pressure cooker

Add the next 8 ingredients to the mix

When the mixture cooks down a pit, add the tomatoes and peas

Cook the mixture for a minute or two to soften the tomato, and then add the cauliflower florets

Add the water

Seal and bring to pressure, holding at pressure for 10 minutes.

Turn off heat and let settle 10 more minutes.

Cool and depressurize the pressure cooker by running under cold water.

Salt to taste and serve, keeping in mind that pea soup starts off thin and thickens substantially over time. If the mixture becomes too thick, ad water and salt as desired.
