Place â…” of the scallions into a small bowl and add vinegar to cover. Season with a pinch of salt and set aside to pickle.Â
In a second small bowl, combine the sesame oil, sugar, 2 TBSP soy sauce, and 2 tsp gochujang (or more, to taste). Stir until the sugar has dissolved.Â
Add a couple tsp oil to a large skillet (preferably nonstick) set over medium heat. Add the sliced carrots, season lightly with salt and pepper, and cook, stirring frequently, until tender. Transfer to a plate. Add a little more oil to the pan, if needed, along with the zucchini. Season lightly and cook until tender, about 3 to 5 minutes. Transfer to the plate with the carrots.Â
Add another couple tsp oil to the same pan, now set to med-high. Add the beef in a single layer, broken up/spread out as much as you can. Let it brown and cook almost all the way through on one side, to get it nice and crispy; takes about 4 or 5 minutes. Add the ginger and the garlic, along with salt and pepper to taste. Stir and cook just until browned all the way through; about 30 seconds more. Drain excess grease from the pan.
Turn off the heat, add the remaining 2 TBSP soy sauce and stir.
To serve, pile some of the hot cooked rice into bowls or onto plates. Top with some gingery beef, the veggies, a lightly fried egg, pickled and fresh scallions, and the sweet sesame sauce.Â
