Boil the eggs: Put eggs in a pot and cover with water by about an inch. Bring to a gentle boil, then turn off the heat, cover, and let them sit for 10 to 12 minutes. Drain and cool in cold water.

Peel and slice: Peel the eggs, then slice them in half lengthwise. Pop the yolks into a bowl and set the whites on a plate.

Make the filling: Mash yolks with mayonnaise and mustard until creamy. Add salt and pepper. If desired, add a tiny splash of pickle juice. Adjust seasoning to taste.

Fill the egg whites: Spoon the filling into the egg whites or use a zip-top bag to pipe it in.

Add the mummy bandages: Lay thin cheese strips across the top in a crisscross pattern, leaving a gap for the eyes.

Make the eyes: Place two tiny black olive slices in the gap to create the eyes. Use a dab of mayo to help them stick if necessary.
