Preheat oven to 400°F (200°C).

Measure flour in a bowl.

Cut margarine into small pieces and add to the flour.

Stir in cottage cheese until a soft dough forms.

If needed, add ice water (2 to 3 teaspoons) until the dough comes together.

Divide the dough into 6 equal parts.

Roll each part into a 3 x 6-inch rectangle.

Spread 1 teaspoon of Dijon mustard on each rectangle.

Place a sausage on top of the mustard.

Roll the dough around the sausage, encasing it completely.

Brush the rolls with water.

Place the sausage rolls, seam edges down, on a cookie sheet.

Prick the top of each roll with a fork to allow steam to escape.

In a small bowl, mix egg and milk.

Brush the egg mixture onto the sausage rolls.

Bake at 400°F (200°C) for 25 minutes, or until golden brown.

Slice each sausage roll into 1-inch pieces and serve hot.
