Chop the onion, potato and zucchini and set it aside
Heat a heavy bottom pan and add the oil in. Add cumin and let it start spluttering. Now add in the garlic and let it roast
Once it starts turning golden color add in the chopped onion and potatoes and let it all roast.
Onion should turn translucent and the potatoes should be cooked 3/4th
Now add in the Chopped Zucchini and the green peas and let it roast for 5-10 mins in medium flame.
Once it's 3/4th cooked add in the 3 cups of salt, water or vegetable stock and let it simmer for 5 mins.
Cool the mix down and blend it to a smooth mix. Soup will get thick because of the starch from the potato. Add water to adjust soup consistency.
This soup can be served hot or cold. I enjoyed it hot with pesto sandwiches.
