In a food processor, pulse the chopped salmon about 10 times, or until minced. Scrape the salmon into a bowl. Mix the mayonnaise with the fish sauce, sambal oelek, garlic, shallot, ginger, lemon zest, 2 tablespoons of the cilantro, 1 tablespoon of the mint, 1 teaspoon of salt and 1/2 teaspoon of pepper. Add the mixture to the salmon along with 1 cup of the panko. Fold the salmon mixture together with a rubber spatula. With lightly oiled hands, pat the mixture into 6 burgers. Cover with plastic wrap and refrigerate for 2 hours.
Meanwhile, in a large bowl, combine the lemon and lime juice with the vinegar. Add the sugar; stir until dissolved. Add the cabbage, cucumber, onion, red pepper and the remaining 1/2 cup each of cilantro and mint and toss well.
In a shallow bowl, mix the remaining 1/2 cup of panko with the sesame seeds. Pat the mixture onto the salmon burgers.
In each of 2 large nonstick skillets, heat 2 tablespoons of the oil until shimmering. Add 3 salmon burgers to each skillet and cook over moderately high heat, turning once, until well browned but barely cooked in the center, about 7 minutes.
Spread the Avocado Aioli on the rolls. Add the salmon burgers, top with the slaw, close the sandwiches and serve.
MAKE AHEAD The uncooked salmon burgers and the slaw can be refrigerated overnight.
NOTES:Sambal is a condiment used in Indonesia, Malaysia, Singapore, the southern Philippines and Sri Lanka, as well as the Netherlands and in Suriname, made from a variety of peppers, although chili peppers are the most common. Sambal is used as a condiment or as a side dish, and is sometimes substituted for fresh chilis; it can be very hot for the uninitiated. It is available at exotic food markets or gourmet departments in supermarkets in numerous countries. --

This recipe replaces the raw egg in many aioli recipes with an Avocado, to acheive the creamy texture, without the risk of salmonella from uncooked eggs.
Also, coriander leaves (cilantro) taste quite different to the seeds (which is what is usually referred to as coriander), so if you cannot get any, flat-leaf parsley is a good substitute.
