Place lentils and 1 cup of broth into a bowl and let soak while preparing other ingredients.
Warm up the Instant Pot by turning on the sauté feature. This will help build pressure faster.
Prepare the rest of chili ingredients by draining and rinsing the beans and chopping the vegetables.
Turn off the sauté feature and place all ingredients into the Instant Pot including the lentils and the broth they're soaking in (and the remaining 2 cups of broth). Mix well.
Close the Instant Pot and turn the pressure valve to seal. Set Instant Pot to > manual > high pressure > and set time to 7 minutes. The Instant Pot will take around 15 minutes to build pressure before it begins to countdown from 8 minutes.
When the timer goes off, quick release the Instant Pot by manually opening the valve. Once the steam stops, remove the lid, and stir.
Serve immediately with your favorite toppings!
