Add the honey, sugar, salt and water to a pan. Stir to mix over medium low heat. Let it bubble up. Continue to cook, without stirring, until it turns light golden brown, 2 - 3 minutes.
Stir in the sesame seeds and nuts. Stir well until everything is well coated with the syrup.
Place the mixture between two pieces of parchment paper. Let cool for a minute. Press it down to flatten it. Roll it out with a rolling pin to make a 1/4 to 1/2-thick rectangle. Using a side of a knife, push in the rough sides to make straight lines. Roll it again to a even thickness, as necessary.
When the crunch is hardened but still slightly warm, cut with a sharp knife into desired sizes.
