Take your whole chicken and sprinkle the inside and out with Salt, Pepper, & Lawrys Seasoning salt. Don't coat it too thick, maybe use total about 1 tablespoon of each on the entire chicken. Wash the can of beer. Take 1/3 of the beer and pour it down the sink, or drink it :-)
insert the Rosemary into the can of beer. Stick the beer inside of the chicken... the top of the can facing the "neck" of the chicken. Grill for 45 minutes to an hour. Carefully remove the can and serve the chicken.
