In a saucepan over medium heat, add the almond milk, olive oil, cornstarch, lemon juice, garlic powder, and salt.
Simmer over low heat, stirring constantly, until the mixture thickens.
Add the coconut yogurt into the pan and keep stirring until the mixture achieves a smooth texture. Transfer to plastic wrap, and wrap it to form a mozzarella-shaped ball.
In a bowl of cold water, add the mozzarella balls and allow to cool for a half-hour. Transfer to the fridge to set for four hours, then slice and enjoy immediately.
