Cut the avocado in half. Remove seed. Scoop out avocado from the peel, put in a mixing bowl. Mash it throughly and add lemon to prevent avocado from browning
Add oil to the pan and saute onion for 2 -3 min and add tomato (I generally do not cook onion and tomato for long time as I prefer my tomato to not became mushy, so cook until raw smell goes off)
Add onion and tomato to the avocado and add salt as needed
To achieve creamy texture, I made avocado smooth but can also try chunky version You can skip even saute part and add raw onion and tomato Can add Chat masala/ cumin powder/ coriander powder to make it Indian style
