Protein Burgers

I have enjoyed, when I choose to eat meat, the protein-style burger at In 'n Out Burger. It is wrapped in big leaves of lettuce (get the grilled onions!). But I have been delighted to find similar items elsewhere -- Carl's Jr. makes their chicken sandwiches low-carb style (wrapped in lettuce). They are wonderful, if you happen to someone that understands your order and it gets made correctly.
Today I enjoyed the turkey burger protein-style at Red Robin. It was moist and hearty; best of all they forgot to give me the side salad it was to come with and gave me seasoned fries instead. I figure I am entitled to eat a few fries if there is no bun!
