Cut the tempeh into quarters and steam for about 5 minutes to remove some of the bitterness. Let the tempeh cool a bit before handling.
Mix the nutritional yeast, crushed red pepper, garlic, turmeric, black pepper, paprika, cumin and oregano in a small bowl and set aside.
Combine the miso, lemon juice, and 2 teaspoons of water in a small bowl and set aside.
Sauté the onion, pepper, and carrots in 2-3 tablespoons of water until softened.
Crumble tempeh with clean hands and add to the pan. Stir to combine.
Add the seasoning mix and stir until well combined. Cook on low heat for 3-4 minutes, stirring occasionally. Add 1-2 tablespoons of water at a time, as needed, to keep the seasonings from sticking to the pan.
Add the miso mixture and stir to combine. Finally, mix in the tomatoes and greens. Cook until the greens are softened.
Serve the dish topped with avocado, herbs, and a fresh squeeze of lemon juice.
