The health factor of a chicken burger can depend largely on the specifics of the recipe and preparation. Generally speaking, chicken is a lean protein source that's lower in saturated fat than beef, making it a healthier choice. However, the ultimate healthiness of your burger also depends on what you're adding to it - such as the type of bun, condiments, toppings, and whether the chicken is skinless or not. Opting for whole grain buns, adding plenty of veggies for fiber, and using healthier condiments can keep your chicken burger on the healthier side.
