Steps

1. Preheat your grill. Lay the two bunches of green onions on the hot grill and cook until they are a little charred on one side. Remove, chop into 1-inch pieces and set aside.
2. Lay the bell peppers on the grill and cook until their skins are blackened on all sides. Remove to a bowl and cover with plastic wrap and set aside.
3. Next grill the steak until it is medium rare. Remove, cool and slice into bite-sized strips. Set aside.
4. Remove the plastic cover from the peppers and remove their stems, seeds and skins with your hands. Slice the roasted peppers into strips and set aside.
5. In a large bowl, whisk together the vinegar, soy sauce, garlic, sugar, sesame seeds and sesame oil and adjust the seasoning with salt and pepper.
6. Add the scallions, peppers, meat and artichokes to the bowl with the dressing and toss. Refrigerate and serve chilled or at room temperature.
