If you like soft meat, then chicken may be more suitable. Chicken is rich in protein and nutrition, and its taste is soft, which won't make the egg burger too heavy.
If you like more chewy meat, you can choose beef or pork, which is relatively hard and can provide a richer taste.
In short, when choosing meat, it should be decided according to personal tastes and preferences, but at the same time, we should also pay attention to the freshness and quality of meat to ensure the hygiene, health and safety of egg hamburgers.
