Heat olive oil in a pan over medium-high heat (preferably a wok).
To the pan add lemongrass, ginger, shallots and garlic. Cook until aromatic 1-2 minutes.
Add red curry paste and cook for 1-2 minutes.
Add calamari steaks and cook for 5-6 minutes until cooked through.
Add fish sauce, sugar and roasted thai chili paste. Taste and adjust according to personally salty/sweet preferences.
In a separate pan lightly pan fry the bok choy in the ½ tablespoon olive oil until lightly cooked but still crispy.
Serve calamari steak over bok choy, sprinkled with sesame seeds.
