To prepare this Lentil Chili Recipe gluten-free, ensure that the V-8 juice (or tomato juice), bacon, and chocolate are certified gluten-free, as some brands may contain additives or be processed in facilities with gluten exposure. Additionally, verify that all spice blends used (such as chili powder and cumin) are gluten-free. The recipe itself does not contain gluten-based ingredients, making it naturally adaptable with careful ingredient selection.
