Set your Instant Pot to the Saute function. Add the olive oil and onions and cook until the onions are translucent. Add carrots and saute for another 1-2 minutes. Add the garlic and saute for 1 minute.
Add the vegetable broth. Use a spoon to make sure you get all the bits from the bottom.
Add the can of crushed tomatos, chopped tomatos, honey, salt, pepper, basil, thyme and parsley. Stir everything together.
Close your Instant Pot and make sure it's sealed. Set your Instant Pot to High pressure to cook for 15 minutes. Your Instant Pot will take at least 10-15 minutes to come to pressure and then countdown the 15 minutes. Let the pressure release naturally for 5-7 minutes. Be careful opening the Instant Pot if there is any remaining pressure.
Use a potato masher or immersion blender to blend your soup. Either of these tools will work depending on consistancy you prefer for your soup.
You can adjust the seasonings at this point if you think your soup needs more salt etc. Serve your soup with a grilled cheese.
