The total preparation time for this meal is just about 20 minutes. It takes a little longer than a typical grilled cheese because you need to add the egg after the first side of the grilled cheese has toasted. So toast one side, use a cookie cutter to make the hole (bonus if it heart-shaped), and then add the egg! Once you add the egg, cover the pan and let the grilled cheese cook for about another 6-8 minutes. Since a grilled cheese sandwich is obviously thicker than a slice of bread, you want to make the hole smaller. My mom always used a cup to make the hole in the bread, but you are going to want to use a cookie cutter to easily cut through the grilled cheese. I used a heart shaped cookie cutter, but most shapes will work. The secret to adding the avocado is to mash it. Sliced avocado is so slippery! You need to mash it. Avocado is a delicious addition to most sandwiches, and it tastes even better when it doesn’t slip out and fall on your plate. If you wanted to… you could add bacon to the sandwich. Because bacon is always a good idea.
