Chickpea Flour Crust: Preheat oven to 350°.
Mix all ingredients. It should be the consistency of play dough. Oil a 9" pan with olive oil, including the sides of the pan. Oil your hands as well.
Spread the dough out in the pan, including the sides, pressing down to get it even. Bake at 350° for 20-25 minutes, or until the edges are starting to turn golden.
Filling: Heat the olive oil in a pan on medium heat. Add onions and cook until translucent.
Add garlic, broccoli, salt and pepper. Cook until broccoli is crisp tender.
Add spinach and cook until it is wilted.
In a food processor combine tofu, miso paste, tamari, and nutritional yeast. Mix well. Add salt and pepper to taste.
Pour the spinach broccoli mixture in. Pulse to combine. Spread over chickpea flour crust. Place sliced tomatoes on top. Bake at 400° for 20 minutes.
