Place the bread slices on a cutting board. Now cut off the crust of the bread slices. Slice them in half lengthwise.
Prepare the filling. Most pinwheel sandwiches have a slice of cheese in them. You can use vegetable or meat deli slices in them. Vegetables like cucumber, radishes and carrots make great fillings. Cut the vegetables and meat in thin strips to make them convenient to be used as a filling.
Use a rolling pin to flatten the slices. This prepares the bread for making a good pinwheel. However, do take care not to tea up the bread with the pressure from the rolling pin.
Place the cheese slices on the bread. Top up with the filling. Roll the bread in length. However, make sure that all the content remain inside and does not spill. Keep the whole roll packed. Wrap it in a cling film and refrigerate it. Chilling the role makes cutting the pinwheels easier. Do it with all four of the bread slices. You can insert a toothpick in the roll to keep it together.
Take out the chilled roll and use a sharp knife to slice. The slices will appear as pinwheels. Place them in a serving platter and serve right away. You can insert toothpicks in all of the wheels to keep them in shape.
