Preheat the oven to 400°F. 

Cut a parchment round to fit into a 10-inch ovenproof nonstick skillet or cast-iron skillet. Set aside.

In a blender or food processor, purée silken tofu, coconut milk, nutritional yeast, cornstarch, tahini, turmeric and black pepper. Set aside.

Heat a large skillet over medium heat until hot. 

Add leeks and cook until beginning to brown and stick to the skillet, about 5 minutes. 

Add a splash of water to the pan and stir well to dissolve any browned bits. 

Add crumbled firm tofu, asparagus, red peppers and olives; cook, stirring occasionally, until vegetables begin to soften, about 5 minutes.

In a large bowl, combine tofu and vegetable mixture with puréed tofu mixture and basil. 

Pour mixture into the prepared nonstick skillet and bake 20 minutes. Remove from the oven and gently run a knife or rubber spatula around the edge to prevent sticking. 

Return to the oven and continue to bake until golden and firm, about 15 minutes. Let rest for 10 minutes before slicing.
