Mushrooms can help make dishes like casseroles, stews and chilis more healthful. Simply cut back on the meat and add mushrooms, which
provide a "meaty" texture and rich flavor.
Heat oil in large nonstick skillet over high heat until hot. Add all the mushrooms and sauté until brown and almost tender, stirring constantly, about 10 minutes.
Add bell pepper, ginger and garlic and sauté 1 minute. Add spinach and green onions and stir until spinach wilts, about 2 minutes. Stir in soy sauce. Season to taste with salt and pepper. Transfer to a serving bowl and serve immediately.
