Heat oil in a deep non-stick pan on medium-low heat and saute onions till tender and lightly browned. Add paneer, and fry till it starts to brown along the edges. Make sure to stir continuously so that the paneer does not burn.
Add in the mixed veggies, spices and dried mint, and fry for a couple of minutes.
Add in rice and salt, and stir well to coat each grain with oil and spices. Pour in water, cover, and cook for 15 minutes till all the water evaporates and the rice is cooked through.
