Add the eggs and the salt into a bowl and beat. Then fold in the cheddar cheese.
Scramble the eggs in that same skillet for 1 minute. Once the eggs are cooked, place them aside.
Grab a clean skillet and let's make a cheese tortilla!
Set the skillet over medium heat and sprinkle with mozzarella in an even layer, making sure the bottom of the skillet is covered evenly.
Cook the tortilla for 2 minutes or until the edges are golden-brown.
