That's right friends, methionine. A wonderful amino acid that can only be had from meat, cheese, Brazil nuts, eggs and seeds. While you can get it in supplement form, it is not as potent as the real thing, and since Brazil nuts go stale and cheese turns green, you're going to end up a little green yourself under those stairs if you don't follow my advice. You're going to have to jerk some beef.
Beef jerky is the perfect food.
Get yourself a plug of jerky, and you're ready to trek the Oregon Trail barefoot. In the snow. The perfect beef jerky is made with quality, extremely lean meat. I like to use an Angus flank steak because the grain of the meat is just right for slicing, and there is so little fat that trimming is almost effortless. Round steak also works well.
