Roughly chop all the nuts using a knife, because if you use a chopper/blender it will more finer than what we are looking for. You can use any nuts of your choice.
Then using a food processor, grind the dates using pulse. In a non stick pan, add one teaspoon of ghee along with all the nuts. Roast on a slow to medium heat, stirring continuously for a couple of minutes. Take the nuts out and set aside. In a meanwhile, add the additional tsp of ghee and roast the poppy seeds. After a couple of minutes, add the chopped dates and mix well with the poppy seeds for a minute.
Now add the roasted nuts and mix everything together so that all the nuts are incorporated with the dates. Let it rest for 4-5 minutes so that it is easy to handle. Make a log and wrap it in the aluminum foil and refrigerate for a couple of hours. Cut them into 1/4 inch slices using a serrated knife.
