Avoiding Slabs of Chicken

I am in a dinner group, the members of which are not aware that I do not eat meat. I am terrible at being sneaky. So terrible.

Today, Trevor--a delightful young man in my dinner group who loves his protein--made giant slabs of chicken with salad and bread. Normally, I can eat the sides and dodge the meat and life is cool. BUT TODAY, Trevor was distributing the meat-slabs.
"Which one do you want?" he inquired politely.
"Ummmm no thank you," I responded in a casual, devil-may-care attitude, turning to the salad as though this were no big deal.
"Hey wait," he said, "You can't skip the main course. That's not normal."
"I," I said quickly, thinking on my feet, "IIII ate a bowl of chocolate cheerios when I got home from school and now I just need healthy food to balance it out."
Trevor narrowed his eyes.
"Chocolate cheerios?"
"Yep. Yeeeep."
"Are you feeling okay?"
"Yeah!" I said with a winning laugh, grabbing my garlic bread and dashing to the couch.
"Okay," Trevor said, "I'll put a piece in a tupperware and you can eat if for lunch."
"That sounds...fantastic!"

Time passed. Small talk was made and a football game played in the background. I waited for the perfect opportunity. When Trevor seemed completely immersed in the game, I leapt to my feet. "Thanks Trevor! Bye guys!" I shouted, making a beeline for the door.
"Wait--" Trevor began to say, so obviously I immediately shut the door and made like a bolt of lightening down the stairs and into my apartment.

...It would probably be better just to tell people that I do not want their meat products.
