Flaked sea salt & fresh ground black pepper, as garnish
Instructions
Heat a cast iron pan over medium heat.
Spread the miso on one side of each slice of bread and then add butter on top of that. Spread both out evenly over the bread.
Place the miso butter side down first into the hot pan. Fry the bread for about 3 minutes until browned and then flip and fry the other side for about another 3 minutes or until browned and toasted. There will be residual miso butter in the pan to give the unbuttered sides of the bread a bit of flavor. That will be the outside of the sandwich.
With the full miso butter side facing up, drizzle vegan mayonnaise on top of both slices. Then add slices of the heirloom tomato and add flaked sea salt and fresh ground black pepper to taste. You can either eat it open face with tomatoes on both sides, or pile the tomatoes as high as you like on one piece of the bread and top with the other piece of bread and slice in half.
