Combine the nuts in a large saucepan or skillet over a medium heat. Toast, stirring intermittently, until the seeds start to pop and everything is toasted. Turn the heat off and drizzle over the Tamari until all the nuts are a golden colour. It will sizzle as you pour.
The only trick to this nut mix is the amount of Tamari you add. It depends on how toasted your nuts are, how high the heat is, etc. You want the nuts to be well flavoured and salted, but not too salty. It helps to have extra nuts on hand in case you overdo the Tamari. Taste and adjust as you go.
Once you’re happy, add the toasted sesame oil if you’re using it. Decant into a large bowl and serve. If you are making it for snacks, allow the mix to cool completely before you divide into reusable containers.
