Destone avocados and scoop the flesh into a bowl. Using a fork, mash avocados. (You can also use a mortar and pestle or food processor).
Add onions, tomatoes, green chilies and coriander (cilantro) leaves. Stir to combine. Add lemon juice. Season to taste with salt, ground black pepper and more lemon juice, if needed.
Add ground cumin and yogurt. Stir to combine. Transfer dip to a serving bowl. Sprinkle with sesame seeds.
Serve with crackers and vegetable sticks.
Notes
- Add more green chilies if you like more of a kick. Deseed them to reduce the heat.
