Using a sharp knife, cut each of the tomatoes in half. Carefully spoon out the insides of the tomatoes and discard, saving the skins as shown.
Next, empty the pesto sauce into a squirt bottle. (I found a great one at my local dollar store). Squirt pesto on the rim of the tomato skins as shown.
Fill each tomato skin with cream cheese. It's ok if things start to get a little messy and the pesto spreads into the cream cheese. This gives the illusion of "infected" eyeballs!
Next, press a sliced black olive into the center of each eyeball. Using the squirt bottle, squirt a small amount of pesto in the middle of each olive.
Finally place 1 or 2 eyeballs over a large basil leaf and skewer with a toothpick. Enjoy!
