WORMS: The other tube meat.

Earthworms can provide an interesting and easy protein. But no one wants to eat dirt...so... here's the Recipe:

Collect 1 dozen large worms
Toss 'em in a coffee can half full of wet corn meal.
After a day and a half they will have replaced all the dirt inside with golden corn.
Fry in oil.
Eat with hot sauce.
What you end up with is kind of like an inside out corn dog.

Worms
Deep beneath in my earthen keep I eat my way to bliss.
And what you find as dirt and grime is really my shit and piss.
I slink and slunk with mouth and butt all day I sweat and toil.
And all of this is not a whim for my true love is soil.
But when it rains...
When clouds shed blood...
When rivers break their banks...
The flood that comes it thins my blood and all the world turns rank.
I cannot dig...
My home a tomb...
I am exposed, alone.
And since I never learned to swim I shall make you my home.

Eat Pigeon!

2000 years ago people carved pigeon farms out of stone. If you're hungry in the city why not manage and utilize what's available instead of looting a failed system. Bet Guvrin Caves – Israel Parks | Holy Exposures

Industrious cave dwellers huh? Reliance on ones effort seems to be underrated.
You can buy a half of one for $11.50! if you want...

... go ahead make a reservation a month ahead of time and visit The Canteen in San Fransisco... OR... Grab a couple in the park and feed them grain for a few weeks until they're fat and clean.
