In a large skillet or wok, heat oil over medium high heat. When hot, Add the onions, garlic, and ginger. Mix and cook until translucent, 1-2 minutes. Add the rest of the veggies and a pinch of salt and cook until golden on some edges, 2 minutes.

Add salt and pepper generously, and mix to combine. Taste and adjust salt, heat, and black pepper. Cover and cook for a minute. Garnish with green onions and serve.
