Whisk all ingredients together. If using a panini maker: pour wet batter onto hot panini maker and close for roughly 30 seconds to 1 minute. Open and if making a cold sandwich remove from panini maker and cool bread then add fillings and fold one side over the other to create a sandwich. If you want a melty sandwich, fill one side with all your favorite toppings, mine was ham, white cheddar and fresh tomatoes. Fold the other side of the bread over top and repress the panini maker down over the closed sandwich until the cheese is melty (about 30 seconds more) and enjoy! If using a griddle or pan: lightly grease the surface, pour batter into 2 square shapes, cook until mixture is mostly cooked then gently flip over for a few seconds to finish the cooking. If making in a microwave: pour batter into microwave safe square Tupperware dish and cook for 45 seconds or until cooked through, let cool slightly then slice in half and fill with ingredients.
