Daileo Paleo: Avocado Chicken Burgers with Grilled Romaine Lettuce I am usually not a big fan of chicken burgers. The red meat carnivore inside me always says, "no thanks." But these are different. The fresh avocado is mixed right into the ground chicken before cooking and the texture of two together just works. Seasoning is a must because chicken can tend to be a bit bland. I added a little diced onion and a touch of cumin for extra flavor.
