Heat some cold pressed olive oil in a fry pan on medium heat. Add both slices of bread and make sure the side that is getting cooked is completed coated with oil. Add a generous amount of vegan mozzarella. Let the bread get crispy and the mozzarella melty.
When both sides a done, remove them from the pan. Add the tomato and close her up. That's it. Enjoy!!! You can add some basil if yo have some. That would be great.
