In a food processor pulse nuts and sesame seeds until they resemble a coarse meal. Keep everything under the size of a pea. (Take care not to over pulse as this will turn nuts into nut butter).
Add this mixture to a dry sauté pan and place over medium-low heat. Give a stir every 30 seconds or so for about 3-4 minutes. Lower heat to low and add the coriander, cumin, fennel, pepper and salt to the ground nut mixture in the pan. Stir for another 3-4 minutes until slightly fragrant.
