1. Saute onion in olive oil for 3-4 minutes. Next, add garlic and saute for an additional minute. Add cumin, coriander, chili and turmeric and continue to cook over medium heat for 4-5 minutes.
2. Add water if the mixture becomes dry; do so 1 tablespoon at a time to avoid making the mixture too runny. Finally, add the mushrooms, tomato paste and salt.
3. You can add more water (anywhere from 3 tablespoons to 1/2 cup depending on the consistency that you personally want to achieve.)
4. Lower the heat to a simmer, cover and allow to cook for 10 minutes. Remove from heat and add the chopped fresh cilantro.
I serve this dish over a plate of couscous.
