Preheat your oven to 180 C. Place a sheet of foil on a baking sheet, lightly butter the sheet to the size of the tortilla used. Place tortilla on the foil.

Place the ham slices, slightly overlapping one another, into the center of the tortilla. Place half of the cheese on top of the ham and create a small well in the center. Crack the egg into the cheese well. Season it with salt and pepper, and top the egg with the remaining cheese.

Fold the sides of the tortilla in toward the center to create a pocket. Wrap the folded tortilla pocket loosely with foil. Center the foil pouch on the baking sheet and bake for 25 minutes, or until the egg feels firm to the touch. Remove the foil pouch from the oven, unwrap it, and allow it to cool slightly before eating.
