Rinse the lentils and pick out any stones.
Finely chop the onion, bell pepper, and garlic and add them to the slow cooker with the lentils, tomato sauce, broth, ketchup, brown sugar, mustard, chili powder, and salt.
Cover and cook on LOW for 6 hours (or HIGH for 3.5) until the lentils are soft.
If it's still soupy, cook uncovered on HIGH for 20 minutes. Mash lightly with a spoon for a meatier texture.
Spoon onto toasted buns and serve with pickles and a slice of cheese for anyone who wants it.
