Even though olive oil is rich in flavour and has many healthy fats and antioxidants, it's not good to use it for frying any sort of food. The reason is that olive oil has a very low smoke point and it will quickly burn. This is very unhealthy and is even linked to cancer based on certain studies. If you want to fry something, I recommend you use a high-quality canola oil or even a sunflower oil. Anything with a high smoke point that is vegetable based. Best of luck!
