Turn the saute function on the IP and set the timer for 7 minutes. Allow the IP to heat up for 2 minutes
Add the onions, carrots, and 1/4 cup of water to the hot IP
Saute for the remaining 5 minutes, stirring frequently and scraping down the sides/bottom
Once the timer ends, add the garlic and stir to combine
Add the lentils, ketchup, maple syrup, chili powder, red wine vinegar, hot sauce, and 4 1/2 cups of water to the Instant Pot. Stir to mix the lentils with the water. Cover with the lid and seal. Set to High, Normal Pressure, Manual cook for 15 minutes.
Once the timer goes off and the IP has finished cooking, allow the lentils to naturally release (NR) for 10 minutes. Once the 10 minutes is up, quick release (QR) the knob if the IP remains pressurized.
Once it is safe to open the IP, add the BBQ sauce and stir to combine.
Serve the lentils on whole wheat rolls (with an optional slice of cheese) and enjoy!
