Rinse and drain the lentils.
Hit the sauté function on your Instant Pot and add ½ cup of vegetable broth. Let it warm for a few minutes.
Add the garlic, diced onions, carrots, and celery. Let them simmer for a few minutes until softened.
Stir in all the spices: chili powder, paprika, black pepper, Worcestershire sauce, and apple cider vinegar.
Turn off the Instant Pot and add the remaining 4 cups of broth, tomato sauce, sugar, tomato paste, and lentils.
Secure the lid and set the Instant Pot to bean-chili 25 minutes, with a 10-minute natural pressure release.
Once the pressure has been released, open the lid and mix the ingredients well.
Serve the lentil mixture on your choice of bread product – whether it's gluten-free buns, pita breads, or wraps.
