How to reproduce beef flavor & texture
If you are loving cows in particular, because they are nice and give us milk, you could substitute some other hooved animal.


I cannot really tell the difference between farmed bison and beef.  You can get bison meat in a lot of grocery stores now.
Venison or elk can be ordered from specialty groceries and also have that serious meat taste.  Or maybe you know a hunter?  Or maybe you can become a hunter!  There are too many deer in a lot of places and it is a waste to just have them get hit by cars.  Some localities are practically begging hunters to come and help with the excess deer.  
Goaty goaty goat meat is arguably the most environmentally sound big quadruped meat.  Goat curry Jamaican style is awesome and now I have a serious goat jones.  Thanks.  
Horse meat is hard to come by in the U.S. but apparently polish horse meat was called beef and fed to British people and they were happy until they found out.  You would think after mad cow they would be happy for a beef substitute.
I had camel meat once in Australia.  It is very much red meat with a serious meat taste.  I see you can order camel meat in the states.  I am thinking of all these camel is the best solution for you.
