Preheat the Oven: Set your oven to 375°F (190°C) and lightly grease a pie dish.
If using tofu, blend it with plant-based milk, nutritional yeast, turmeric, black salt, and spices until smooth.
Whisk chickpea flour with water, plant milk, and seasonings until a thick batter forms.
Warm up a pan over medium heat and drizzle in some olive oil. Let it heat up until it shimmers, ready for cooking!
Sauté onions, mushrooms, and bell peppers for 3-4 minutes until softened.
Stir in spinach and cook for another minute.
Mix the sautéed veggies into the blended tofu or chickpea flour mixture.
Pour the mixture into your greased pie dish, smoothing out the top.
Bake for 35-40 minutes until the quiche is firm and lightly golden.
Give the quiche about 10 minutes to cool before slicing—it’ll set nicely and be easier to serve!
