Forbidden foods...

I'm not sure if I am the only one but all I am craving (now that my appetite has come back) is tuna and turkey subs from the deli. Obviously tuna isn't a safe choice and I've been told deli meats aren't either. 
I've had a few sandwiches since I found out I was pregnant, but I keep on having the cravings! 
Is anyone else experiencing this!? 
Maybe I just want the foods because I was told not to eat them lol.
