In a large bowl soak the lentils for about 10 minutes. After 10 minutes, add the lentils to the instant pot. at 1/4 of onion, and salt or bullion of your choice (I used 2 veggie bouillon cubes).
Set the instant pot to bean/chili for 20-25 minutes. Seal the vent and let it cook.
In a small pot add some water and set it to medium heat. Add 1/4 onion, 2 tomatoes, and 3-5 dried chili peppers (add more if you want it spicer), and boil for a few minutes.
After 5-7 minutes add these ingredients to a blender, add salt or veggie bouillon to taste and blend.After the instant pot beeps, vent out the steam and add the tomato puree.
Place the lid back on the instant pot and let it cook for 5-7 minutes.Vent the pot, Serve, garnish with a little cilantro (optional), and enjoy.
