Is this funny? is my boss or myself autistic?

I was starving at work and there has been a frozen dinner in the freezer so long either the owner was fired or forgot about it so i decided to eat it. while i am eating it the treasurer Kelly says "what are you eating" i lifted up the box and read "Vegetarian Lasagne" she said "i didn't know you were a vegetarian" "i said i'm not, the Lasagne is" she apparently thought it was hilarious.
