Shrimp and fish tacos. A 1 pound sirloin steak. Really good mash potatoes and gravy. Very good buffalo chicken wings. Guacamole and pepperoni pizza. Carne Asada nachos with everything on it, lol. And last but not least, liver and onions, lol. :)
Edit: How about a wormhole? Since people don't know what it is, people don't know if it is edible or not, lol. You can just claim that it is, lol. And when they bring it to you, just jump through it, lol. :)
