In a large bowl, whisk together oil, water, chilies, tandoori masala, chat masala, red pepper flakes, minced garlic, garlic powder, smoked paprika and mint leaves. Mix until a liquid paste has formed. **If paste mixture is too thick, add in an additional 1/2 tbsp of water to dilute** Toss in cauliflower & chickpeas. Mix until all ingredients are incorporated. At this point, taste test the mixture and adjust seasonings as needed. For additional spice: sprinkle 1/2 tbsp of tandoori masala on top and mix well.
