Bring a Subway footlong, made without dressing. They'll give you mayo, oil and vinegar in packets you can bring along, keeping your sandwich from getting soggy during the hike. Get lots of onion and colorful vegetables, so that it's all the more crunchy and fragrant when you eat it.
Jiffy Pop in the stove-top shaker style, and use it either over a corner of your fire or the camp stove.
Stash a Dutch Oven in your buddy's pack and make cobbler, to share.
Freeze some cocktail sauce, horseradish and 6 big shrimp from the grocery, and make a shrimp cocktail in your cup. Bring a clear plastic cheapo cup, a hunk of celery and the fixings for a Bloody Mary, which you will ceremoniously create and then enjoy with your shrimp cocktail before dinner. THEN, make the Mountain House, "because it's just so easy". Ha ha!!
Pre-boil a Johnsonville Brat and pack it in with a skewer, some onions and a nice roll. Sear the dog over flame for heat and effect, and make yourself a nice, steaming sausage sandwich for lunch on the trail.
