Use a large, non stick skillet to pan roast the nuts over medium high heat. It doesn't take long and there's less chance of burning them if you do it on top of the stove. Give the pan a shake every once in a while. You'll smell it when they start to roast.
Transfer the toasted nuts to a large mixing bowl to cool.
Use the same skillet and repeat the process with the seeds. As with the nuts, you'll be able to smell it when they begin to toast. You may also hear some crackling. Don't forget to shake the pan to help prevent burning. Set about 1/4 of the toasted seeds aside.
Add the rest to the toasted nuts in the bowl and stir to mix. Allow to cool.
Working in batches if necessary, chop the nuts and seeds into small bits with a food processor. Avoid over processing because you'll eventually make nut butter.
Return to the bowl and stir in the seasoning and reserved seeds. Taste and make adjustments as necessary.
Store in an air tight container in the fridge for a week or two.
