Turn the Instant Pot on sauté mode.
Pour the oil into the inner pot. Allow the onion to heat up.

While the eggplant is sautéing, add the sliced zucchini on top of the eggplant.
Add the garlic powder, herbs, salt, and pepper. Stir the mixture.
Drain the whole peeled tomatoes from the can and put it on top of the ingredients in the inner pot.

1. Turn off the sauté mode by pushing the KeepWarm / Cancel button. 2. Turn on the pressure cooking mode by pushing the Manual button.3. Check the pressure cooking mode is set to High Pressure. If it is not, turn on the high pressure mode by pushing the Pressure button.
Set the timer to 5 minutes by pushing the plus + and minus - buttons on the control panel until you get to 5.
Once you've correctly configured the Instant Pot, wait 10 seconds for the settings to lock. You will see the control panel display On when the Instant Pot is starting to pressurize.
When the Instant Pot is ready for pressure cooking, it begins the count down. Your ratatouille is cooking under pressure now. Hooray!
Once the pressure cooking is done, turn off the Instant Pot by pushing the KeepWarm / Cancel button. Very carefully turn the Steam Release Valve to depressurize the Instant Pot. Once the Float Valve drops to indicate the Instant Pot is no longer pressurized, remove the lid.
Turn on the sauté mode again. This step is optional. You can skip it if you're short on time or don't mind soupy ratatouille.
If you choose to sauté to finish the ratatouille, allow the ratatouille to sauté for 5 minutes. Then it is ready to eat or freeze for later.
