Heat Eggos on a plate in the microwave for about 30 sec-1 min until soft and no longer frozen.
Heat a greased skillet over medium heat until water sizzles. This shows that the pan is hot and ready. Grease it once it's warmed up.
Lay the waffle in the pan and cook until golden, flip, and then cook the other side until golden as well.
This should be about 2 minutes per side.
