Cut the avocados into half and scoop out the flesh into a bowl with a spoon and mash it with a fork.
Add lime juice + salt + paprika + garam masala and mix well. Taste and adjust the spice and salt as needed. Once that's done, add onion, tomato and cilantro.
Also add 1 seed of avocado in the bowl to retain the color as avocados tend to turn black once it comes in contact with air.
Cover the bowl with a plastic wrap and refrigerate or serve immediately.
