*Pre-heating the olive oil on low-medium heat is important for two reasons:
1. Extra virgin olive oil burns easily and this helps prevent that from happening (but it's still possible, so be sure to keep an eye on it as it's preheating. It normally takes me about five minutes, but this can vary depending on the pan).
2. Both garlic and red pepper flakes can burn easily if added to extremely hot oil and these are the first ingredients to go into the saute pan.
