Heat the vegetable oil. Add the onions and garlic and saute until the onion starts to brown.
Add the ginger garlic paste, saute for 30 seconds, then add the powdered spices--turmeric, coriander, cayenne and paprika. Mix well, then add the tomato paste and saute for a couple of minutes until the tomato darkens a bit.
Crumble in the vegan sausage and mix well. Sauté for a couple of minutes until some of the fat oozes. If using lentils instead of the meat, sauté a couple of minutes and proceed to the next step.
Add the vegetables--turnips, potatoes, carrots, bell peppers and zucchini. Season with salt, mix well, and add 2 cups of the vegetable stock. Cover the pan and let the veggies cook over medium heat for about 10-15 minutes or until they are tender. Once the veggies are cooked, you can add more vegetable stock or water if you want a thinner curry.
Add the kitchen king masala or, if using garam masala, add that and the kasoori methi, crushed between your palms. Mix well and season with more salt as needed.
Turn off the heat. Garnish with cilantro and serve hot.
