Well, I'd say it works marginally well. I must admit we didn't go to any great lengths to fix these burgers properly. No guacamole like you see on the box. We didn't really even have hamburger buns. We just used some gluten-free brown rice bread we had in the fridge...which you can get at Trader Joe's, by the way. We did try them first without the fixins, but in the end I think we topped them with ketchup and mustard.
At $3.49 for 4 patties, it's not a bad value. But the flavor left a bit to be desired. You could taste a little chicken type flavor, but the chile and lime kind of failed to come through. And that, unfortunately, was the primary reason we wanted to try these exotic-sounding burger substitutes. There's definitely a hint of lime, but the chile was extremely subtle...a little too subtle for both of our tastes. Now, if you were to add some chile and lime of your own, you might get a more pleasing result. But that kind of defeats the purpose of buying chicken burgers that are supposed to be chile-lime to begin with. There's very little spiciness, and not much tang, either.
If you're looking for a reasonably priced chicken burger, these might be a viable option for you, but just don't expect much from the "chile lime" part of the product. Sonia gives them a 3.5 out of 5, and I give them a 3. Bottom line: 6.5 out of 10.
