Turn on your Instant Pot and select the sauté function. Add the avocado oil and let it heat up. Once the oil is hot, add the chopped onion and bell pepper. Sauté for 2-3 minutes until they begin to soften and turn translucent.
Stir in the vegan minced meat and continue sautéing for another 2-3 minutes. Cook until it starts to brown slightly.
Cancel the “Sauté” function. Add beans, sweet corn, and spices. Stir the mixture thoroughly to combine all the ingredients evenly. Carefully pour the vegetable broth into the Instant Pot.
Select the "Pressure Cook" setting and set the timer for 3-4 minutes at high pressure.
Once the cooking cycle is complete, allow the Instant Pot to perform a natural pressure release for about 2 minutes, and quickly release.
Taste and adjust the seasoning. Enjoy your homemade Chili sin Carne.
