Step 1

Brown ground beef in large pot (or Instant Pot sauté setting) and drain out fat.

Step 2

Add remaining ingredients, bring to a boil. Then simmer about 1-2 hours, stirring occasionally. If using zucchini in place of olives, add them during the last 15 minutes of cooking.

Step 3

Add all remaining ingredients to the slow cooker.Cook for 3-4 hours on high or 6-8 hours on low.

Step 4

Once the beef has browned in the Instant Pot, add the other ingredients. Lock the lid and ensure the valve is set to sealing. Set the pressure cooker to manual high pressure for 10 minutes.

Step 5

After the timer goes off, let the pressure naturally release for another 10-15 minutes. Set the valve to venting to release any remaining pressure.
