Start by slicing and deseeding the red bell pepper. Chop the onion and cut the russet potato into 1 inch cubes. Then mince the garlic clove and cut your smoked sausage into 1 inch circles. Wash and trim green beans if needed.
On the control panel of the Instant Pot, press the Sauté button and wait for it to say Hot.
Add olive oil and smoked sausage. Stir frequently until sausage is browned, about 1 minute.
Next, add onion and sauté the onion until it's soft.
Next, stir in the garlic and red bell peppers.
Add chicken stock and deglaze the bottom of the pot with your stirring spoon.
On the control panel of the Instant Pot, press the Cancel button to end the Sauté mode.
Add the green beans in an even layer, then add the potatoes on top and season with salt, pepper and garlic powder. Do not stir.
Secure the lid on the Instant Pot. Press the Manual or Pressure Cook button and cook on high pressure for 1 minute by adjusting the time using the +/- buttons.
When pressure cooking for 1 minute has completed, push the quick release button to release the pressure.
Once the Instant Pot has depressurized and the float valve has dropped, open the lid.
Now let's thicken up the sauce a bit. To do this, press the Cancel button and then press the Sauté button. Simmer and stir for 30 seconds and then your dinner is ready. Be sure to press the Cancel button to end Sauté mode. Enjoy!
