I’ve been wanting to do this for the longest time. In essence, a burger is not much different from a sandwich, but i think it looks prettier, especially when you have a smooth and shiny bun. Well, my bun was certainly far from achieving that intended effect, but it was ok.
I managed to use the egg whites to make breadcrumbs stick to the chicken patty, and the the egg yolk as egg wash for the bun, so it was just perfect. The chicken patty was just leftover chicken breast meat very simply marinated with salt, pepper and smoked paprika. The breadcrumbs are optional really, as the chicken will taste pretty good if seared nicely. Overall, this was easy to make, healthy and tasty enough.
