According to the information of China Food Network, potatoes, eggplant, green peppers and pen fish can be fried together, because there is no conflict between these ingredients, and frying together will not produce harmful substances and will not affect their nutritional value. In addition, these ingredients are common vegetables and meat, which have high nutritional value and can provide a variety of nutrients needed by the human body.

In the process of cooking, we should pay attention to the adjustment of heat and cooking time to ensure that different ingredients can be cooked at the same time, while maintaining their own taste and flavor.
