Yum, I loved smoked trout (or smoked salmon) and I love asparagus. These burgers are super easy to make in my food processor, basically, throw ingredients in the food processor in the designated order and pulse until combined. Then shape the mixture into burger patties, cover and chill for 30 minutes. While that was chilling mixing together the asparagus tzatziki is simple - blanch the asparagus, shred it (except for the tips) and mix that shredded asparagus into some natural yoghurt, along with some salt, pepper and mint. Delicious.
The burger was delicious, a great smoky, fishy flavour The asparagus tzatziki was good too - I like mine quite lemony, so I added some lemon juice in, which definitely worked with the fish.
