Preheat oven to 200°C. Line a large baking tray with baking paper. Sift flour into a large bowl. Add margarine. Using your fingertips, rub butter into flour until combined. Make a well in the centre.
Pour milk into well. Using a flat-bladed knife, stir until mixture is almost combined. Using your hands, bring dough together into a ball. Turn onto a lightly floured surface. Gently knead dough until almost smooth. Using a rolling pin, roll dough out to a rectangle.
Spread pasta sauce over dough, leaving a 3cm border along both long edges. Sprinkle half of cheese over sauce. Roll up dough firmly like a Swiss roll. Cut into relevant number of slices.
Arrange scrolls close together on prepared tray, ensuring join is turned inwards so scrolls don't unroll while cooking. Sprinkle with remaining cheese.
Bake for 18 to 20 minutes or until light golden and cooked through. Serve
