You can't evade if you don't preserve yourself.  If you let your diet
go or get a case of food poisoning, you're history.  You have to eat.
No 7-11's in the woods, so you will have to go native, and eat what's
available.

Most often in an E&E situation you must feed yourself on the run.  
Snake, birds and rodents are great, But it takes a ton of lead time
to catch them.  You are better off with ants, Termites and grubworms,
because these are plentiful and take very little stopping time to
catch and prepare.  Even grasshoppers take some time and energy to
catch.  Ants, termites and grubworms are the fast food of the 
jungle.  Just think of this as the escapee's Kentucky Colonel.  You
can even sing, "We do termites right."

Turn over a rock and catch a bunch of ants on a leaf or piece of 
paper.  Scoop them into a cup, add water, heat 'n serve.  It will
taste sweet.  Break off a bottom chunk of wood to find termites, and 
flick these into the same cup.  Incidentally, replace the log so that
trackers won't know what you're eating.  Add water, boil; enjoy.

Grub worms go down like a large pill.  Break off the head and swallow
the body with a swig of water.  These are best because the fat content
provides you with energy.

With enough lead time developed to enable you to build a small fire,
you can upgrade your menu.  Rodents, birds, squirrels, etc, make 
great meals.  A fat rat isn't much less than a skinny rabbit.  I am
not in favor of snakes because the risk isn't worth the low fat
diet they provide.  Birds can be snared alright, but they take a long
time to prepare, and you have to boil any carrion-eater because they
are full of parasites.  Fowl are wonderful to eat, but they make a
racket you would not believe when snared.

Plants are another chapter entirely, but as a rule grasses are edible
unless they have saw toothed edges; this will tear up your digestive 
system.  Avoid eating any plant with a mily sap, except dandilions, 
which are fine to eat cooked or raw.
