Add the chopped asparagus and extra virgin olive oil to a nonstick frying pan set to low-medium heat.
Cook for 6-8 minutes or until the asparagus has softened slightly, stirring often.
Preheat the oven to 350 degrees Fahrenheit.
Transfer the asparagus to a large mixing bowl.
Add the tofu, plant-based milk, nutritional yeast, onion powder, black salt, table salt, and turmeric to a blender or food processor, then blend until smooth.
Transfer the blended tofu mixture to the mixing bowl with the asparagus.
Add the spelt flour to the mixing bowl, then stir to combine.
Transfer that mixture to a 9 inch round baking pan lined with parchment paper, then use a spoon to spread it into an even layer.
Bake for 50 minutes.
Let the frittata cool off for at least 15 minutes before serving.
