Pickled Onions
- In a microwave safe glass dish, combine vinegar, salt, and sugar. Microwave for 2 minutes or until the seasonings are dissolved and the liquid is hot. In a sealable container, add the onions and pour over the hot mixture. Place in the refrigerator overnight.
Parmesan Aioli
- In a bowl, combine all the ingredients and refrigerate until assembly.
Steak
- Grill steak to desired doneness, and rest for 15 minutes. Slice thinly against the grain.
Assembly
On your favourite toasted bread, spread a thin layer of the aioli, and top with some arugula. Arrange some thinly sliced meat, and add some pickled onions. Finish with a drizzle of the aioli, and a sprinkle of flaky sea salt. Serve immediately!
