Step 1) Kill a sheep
Step 2) build fire. Even a crappy rotten willow fire will produce good results
Step 3) salt and pepper, or for a pro move, 1 soy sauce ramen noodle seasoning packet
Step 4) cook it over the fire. A little bit of charring is ok, but don't go crazy. A nice flat rock can make a stellar cook surface (see below)
Step 5) devour
your life should be changed at this point
