Butter two slices of sourdough bread on both sides (i.e. butter all four sides) and sprinkle with sea salt. Bring a skillet to medium heat and toast the bread slices until golden in colour, then flip and toast the other side.
Once it's ready, finish by lathering each toast with 2 heaping tablespoons of vegan mozzarella. Season with sea salt and pepper. Then flip one slice of bread onto the other to make a sandwich.
