Turn on the Instant Pot and select the Sauté function. Add olive oil to the pot and let it heat up.
Once hot, add the diced onion and sauté for about 2-3 minutes until it becomes translucent.
Add the minced garlic, diced carrots, and celery to the pot, stirring well. Sauté for an additional 3 minutes.
Add the diced zucchini, bell pepper, and green beans. Stir to combine, allowing all vegetables to sweat for about 2 minutes.
Pour in the can of diced tomatoes (with juices) and vegetable broth. Stir well.
Sprinkle in the oregano, basil, thyme, and add the bay leaf. Stir to integrate the seasonings evenly.
Add the drained kidney beans to the mixture.
Close the lid of the Instant Pot, ensuring the vent is sealed. Select the Soup setting or cook on high pressure for 5 minutes.
Once the cooking cycle is complete, allow the pressure to release naturally for about 5 minutes, then switch the vent to release the remaining pressure.
Open the lid carefully and remove the bay leaf.
Stir in the pasta and switch the Instant Pot back to the Sauté function. Cook for another 5-7 minutes or until the pasta is tender, stirring occasionally.
Season with salt and pepper to taste, adjusting as necessary.
Serve hot, garnished with fresh chopped parsley for a burst of color and flavor.
