Lettuce could be constructed by marinating and pounding out filets very flat and then flash-frying them. Rocky Mountain Oysters might be Brussels Sprouts. Chicken is malleable enough that good slicing and dyeing would simulate a wide range of veggies like peppers, squash, etc. Coarsely ground turkey, fried, is corn.
Beverages are tougher, because you can only drink so much blood really. I think we'd have to work with alcoholic cocktails mostly and substitute shrimp for onions and olives. One could always just pour a big glass of icewater and use super-cold frozen beef cubes for ice, too!
For dessert, candied suet! Meatloaf cheesecake! Filipino "chocolate pudding"! Or just a nice hot cup of beef tea cappuccino.
The variations are only limited by our imagination, and this is America! We're a can-do people.
I've been talking back and forth about this project lately with this gal Michelle I sort of half know. The other day I told her I was making a tomato out of lamb stew meat, and she asked about pickles. My response: "Some people just use sausages and green paint to make pickles but where's the challenge? I like to marinate some finely sliced pastrami in a vinegar mint dressing for a week to get that greenish tinge and then wrap it very tightly and concentrically until a long, wide, firm, bumpy true cucumber of meat is produced. Bon appetit!"
I bet she asks me out now. Women love artists.
