Preheat the oven to 350°F (180°C).

Separate the egg whites from the yolks.

Whisk the egg whites until they are foamy but not stiff.

Beat the egg yolks with the cumin, salt, and pepper.

Gently fold the whisked egg whites into the yolk mixture.

Pour the mixture into a rimmed baking sheet or jelly roll pan and bake for 15 minutes.

Meanwhile, cut the ham into strips.

Mix the cream cheese with the chopped chives, and season with salt and pepper.

Remove the omelette from the pan.

Spread the cream cheese mixture over the omelette and top with the ham strips.

Roll up the omelette. You can let it cool if you prefer it cold.

Serve with a green salad.
