In a medium-size bowl, add avocado. Using a fork, mash the avocado until it is smooth. Season with ½ teaspoon of salt or to taste.
Place 1 tablespoon of butter spread in a large skillet over medium heat. Once butter spread begins to bubble, carefully break eggs and place in pan. When the egg white turns opaque, about 2-3 minutes, flip egg over to cook the second side for additional 2-3 minutes. Season with the remaining ½ teaspoon of salt.
Spread the remaining butter (approx. one Tablespoon per sandwich) on each ciabatta half. Place on a large cutting board, butter side down. Spread uncut side of each ciabatta half with avocado mixture. Add the egg and slices of bacon to the bottom halves. Top each with a tomato slice and the top portion of the ciabatta roll.
Place sandwich in the panini press, gently closing the lid. You will notice as the sandwich cooks, it will start to flatten on its own. Halfway through cooking, rotate the sandwich. This helps to flatten the sandwich without firmly pressing in the beginning and breaking your egg yolk.
Remove from the press and serve warm.
