1. Melt butter in a large saucepan over medium-low heat. Add onion and garlic, and cook until onion is translucent, about 6 minutes.
2. Add wine, and cook until most liquid has evaporated, about 1 minute.
3. Add tomatoes, stock, and oregano, and bring to a boil.
4. Reduce heat, and simmer gently until thickened, 30-45 minutes.
5. Using a slotted spoon, remove herbs. Puree soup in small batches until smooth. Return to pan, and slowly pour in half-and-half, stirring constantly. Season with salt and pepper.
6. Meanwhile, make the bugs: Use a toothpick to pierce each Kalamata olive 4 times (all the way through to other side). Insert a rosemary leaf into each hole to make eight legs. Insert two pieces of chive into the small hole at the end of the olive to make antennae.
7. Make the eyeballs: Using a small melon baller, scoop out a hole from each bocconcini. Halve each pimiento-stuffed olive crosswise. Place a half, cut side out, in the hole in each bocconcini to make eyeballs.
8. Ladle hot soup into shallow bowls. Float 4 or 5 eyeballs in soup, and place a bug on rim of each bowl.

Serves 6.
