Heat 1 Tbs oil in a large sauté pan. Sauté the spinach until just wilted. Turn off the heat, and season to taste. Stir in the sesame oil, 1 tsp soy sauce and garlic powder. Remove the sesame to a small bowl.
Sauté the zucchini slices, or whatever other vegetable you are using, until just tender and add a pinch of salt. Remove the zucchini to another bowl.
Add a little bit more oil to the pan. Over medium high heat, brown the ground beef. Season with a pinch of salt.
Once all the beef is brown, add 2 of the chopped green onions, the brown sugar, 1 Tbs soy sauce, and sriracha. Mix everything together, cook for about another 1-2 minutes, and turn off the heat.
Assembly: add even portions of each cooked ingredient to your base. Top with egg and kimchi. Drizzle with sesame oil or sriracha if desired.
