Heat oil in a non-stick wok on medium-low heat and saute onions till tender and lightly browned. Add in spices, and fry for a few seconds till fragrant. Be careful not to let it burn.
Add in chopped tomato, and fry till it starts to soften. Add in paneer, season with salt, and stir fry till paneer is completely blended with the spices.
Garnish with cilantro leaves and serve.
