Which of the following foods is commonly prepared using the stir-frying technique?

The choice of vegetables and small meat pieces as the food commonly prepared using the stir-frying technique is accurate because stir-frying involves cooking food quickly in a small amount of oil over high heat. This method is ideal for small, uniform pieces of food such as sliced vegetables and bite-sized pieces of meat.

Stir-frying allows for rapid cooking while retaining the food's texture, color, and nutritional value, making it a popular method in many Asian cuisines. The high temperature creates a quick sear, providing flavor and preventing the food from becoming mushy.

In contrast, methods like preparing whole grains or large cuts of meat would not work well with stir-frying because such items require longer cooking times and different techniques to allow for even cooking and texture development. Likewise, soups generally require simmering or boiling, which is distinct from the quick, high-heat method of stir-frying. Thus, the focus on small, bite-sized ingredients captures the essence of the stir-frying technique perfectly.
