In a food processor, place drained and rinsed chickpeas, olive oil, tahini, lemon juice, garlic, salt and cumin. Process and scrape the sides down.
Because lemons have varying levels of juice, you may need to add more lemon juice to taste. If the hummus is too thick, add more olive oil to loosen it up.
Process until very smooth. When you think you're done processing, process for another 2 minutes. Trust me, this is how you get the creamiest hummus ever.
Taste and adjust seasoning
Spread humus in a bowl or plate
Make Topping
In a small frying pan, add 1 tbsp Extra Virgin Olive Oil and cherry tomatoes. Cook on high heat until tomatoes start to blister and pop but not fall apart. This should only take 3-5 minutes, depending on your stove-top.
Spoon warm tomatoes over hummus
Sprinkle Za'atar spice mix over the top. Use as much or as little as you like. Sprinkle chopped parley if using. Drizzle Extra Virgin Olive Oil if using.
