Guacamole/Avocado Dip

I had some ripe Avocados,made Milkshake and with the two left I made this Guacamole.Guacamole is an Avocado dip or spread you can use for your toasts or as a spread in sandwiches or simply as a dip for your chips or snacks.
This is a very easy to prepare recipe with just a few ingredients.Usually I like drizzling a little olive oil in most of my dips and salads so I have added 1 tsp of Olive oil here also it is completely optional,also my children don't like biting tomatoes in their salads or in such dips,so usually I don't add them but here I have added a little.You can either add or omit.
