In a Glass measuring cup, crack and separate Eggs, keeping only the Egg Whites in the measuring cup. 

Place the egg yolks in a separate dish, and save to use at a later time. 

When you've finished separating the Egg Whites, pour the egg whites into the mixing bowl of a stand mixer, and add the cream of tartar, and salt, and mix on Medium until you see a lot of little bubbles forming across the egg whites. 

Turn your mixer up one speed,  for about 1 minute, and you'll see more little bubbles.

Turn the mixer off, and add the Vanilla, and add the Sugar two Tablespoons at a time, mixing after each addition until all the Sugar is added, and dissolved.

Add the Green Food Coloring Gel until you get the bright green color you desire.  

Turn the mixer on high, and beat the egg whites with the Whisk attachment until they form thick stiff glossy peaks, about 5 - 7 minutes - (see photo). 

Turn the mixer off once the egg whites are at this stage.  Place the egg whites in a piping bag with a large tip, and pipe the Egg Whites onto a Parchment paper lined cookie sheet in a swirling motion, coming up to a point.  If you don't want to pipe the Meringues, you may spoon them onto the Parchment paper, by the Tablespoonful. 

When you have filled the parchment lined cookie sheet, place it in the oven at 250 degrees for 1 hour, then turn the oven off, and leave the Meringues in the oven for an hour with the door closed. 

After one hour, remove the Meringues from the oven, and completely cool on the parchment paper lined cookie sheet.

When the Meringues are completely cool, make the chocolate for decorating the faces.

In a small bowl, melt 1/3 - 1/2 cups of melting chocolate - I used Chocolate Almond Bark, and I used about 2 1/2 - 3 of the squares it comes in.  You can use any melting chocolate you have. 

Melt in the microwave for about 1 1/2 minutes, stopping every 10 - 15 seconds to stir the chocolate. 

When the chocolate is melted, add about 3 drops of Black food coloring Gel, and stir to blend. 

Place the melted chocolate in a small plastic piping bag, and snip a tiny portion off the end, or point of the bag. 

Pipe the mouth and eyes onto the Meringues, until you have formed the faces.  Each one will be different, which gives these a whimsical flair.
