Cut paneer in half lengthwise.
Heat a nonstick pan (I like the Always Pan) over medium to medium-high heat (all stoves are different), wait for a minute for the pan to get hot, then add ghee and once it melts, add the paneer and fry for 1-2 minutes, then flip over and fry for another 1-2 minutes, or or until mostly golden brown. Take the paneer out and set it aside on a plate for now.
Combine the filling ingredients in a bowl and mix well. Put the filling in between the two slices of fried paneer.
Add the sauce ingredients to the pan and mix well, bring to a simmer and then cook for 1-2 minutes or until slightly thickened.
Pour the sauce overtop and garnish with a heavy cream drizzle, cilantro, and chopped pistachio. Slice and serve!
