Whisk eggs, milk, salt, and pepper in a bowl.

Melt butter in a skillet over medium heat. Scramble the eggs until set, then divide them into six portions.

Layer one pancake, egg, cheese, sausage, and another pancake.

Wrap each sandwich in parchment paper, place them in a freezer bag, and freeze.

To serve, microwave one wrapped sandwich for 1 1/2 to 2 minutes, turning halfway. Let it cool briefly before handing it to a child.
