Hey guys,
This made a difference and I was pleasantly surprised. I always thought marinading with fish sauce would be too much, but it worked great.
Then I borrowed a tip from the Le Pigeon cookbook where I dressed lettuce with an aioli and topped the burger with it. This incorporated the aioli, but didn't quite treat it as a sauce. It worked really well.
Then I brushed a toasted pretzel bun with dijon and ketchup and added some bacon between the burger and dressed greens. It was very good.
