When food is not uniform in size and shape how should it be arranged for microwaving?

1. Place larger pieces toward the outside of the platter and smaller pieces toward the inside.

2. Arrange food in a single layer and don't overlap pieces as this can cook them unevenly.

3. When possible, turn the food over halfway through cooking time to ensure even heating.

4. Check the food regularly and adjust cooking time as needed to avoid overcooking the items.
