I am not an expert on Mexican food so I am not really sure how you should make nachos. I am basing this on all the nachos I have eaten which are crunchy tortilla chips topped with all kind of ingredients including cheese and then melted. It is a great snack that is very easy to put together. I must admit I was not sure how the combination of Thai chilli and basil stir fry would go with melted cheese… but it did!!
