Jalapeños range in heat. Before adding one to a recipe, I taste a small bit; if it's really hot, I add less. Fennel has a licorice flavour and adds a nice crunch to the chili. Always rinse canned beans before adding them to a recipe to remove any excess sodium. You can replace the extra-firm tofu with tempeh; this will add more texture and a nutty, mushroomy flavor.
