Cooking beans on a grill fired with natural charcoal results in a taste sensation unmatched by other methods.  Below is 2 lbs. of adult Limas cooked in a large Dutch Oven on the grill.  The magic ingredients are simply salt, pepper, a dash or four of Cajun seasoning, onion chopped in big pieces, a couple of large garlic cloves smashed, a quart Ziploc bag full of leftover smoked Boston Butt pork shoulder, and some leftover smoked pork sausage.  Hey,, it's something to do in the outdoors.  This was so delicious, it would make a bulldog hug a hound.
