Rinse lentils: Place red lentils in a fine-mesh sieve and rinse very well under running water until the water runs clear. Drain thoroughly.
Combine: In a medium pot, combine the drained red lentils, oats, nutritional yeast, ginger powder, garlic powder, turmeric, coconut aminos, chopped greens, and sliced mushrooms. Add the broth or water.
Cook: Bring the liquid to a gentle boil over medium-high heat, then reduce to a low and simmer uncovered for about 20 minutes, or until the oats and lentils are cooked. Stir occasionally, until thick and creamy.
Season: Taste and adjust seasonings. Add salt and black pepper to taste.
For serving: Serve warm with a generous pinch of omega seed topping, if using.
