To make the seasoning, add all seasoning ingredients to a bowl or jar and mix.
Prep onion, bell pepper, garlic, jalapeno (optional) and olives as noted.
For the instant pot:
Place the beef in the instant pot. Break it up into small bits with a wooden spoon. Pour 1/2 of the seasoning mix over the beef and mix.
Add all remaining ingredients, including the rest of the seasoning mix, to the instant pot. Stir to mix.
Place the lid on the instant pot and close the pressure valve. Press the "soup" button.
Allow the cooking cycle to complete and then quick release the pressure.
Open the lid when safe to do so. You may need to break up the beef into smaller pieces at this point if needed. Taste soup and season with additional salt and pepper as desired. Spoon into bowls, top with desired toppings and enjoy.
For the slow cooker:
Follow steps 1-4 above, placing the ingredients in and mixing in your slow cooker.
Cook on high for 3-4 hours or on low for 6-8 hours. Taste and season with additional salt and pepper as desired. Spoon into bowls, top with desired toppings and enjoy.
