Vegan Gourmet Grilled Cheese Sandwich

Heat the olive oil in a skillet over medium heat, then add the sliced onion and salt. Cook, stirring occasionally, for about 10-15 minutes until the onions have caramelized. Set onions aside.

Preheat another skillet or griddle over medium low heat and add a thin layer of vegan butter to the pan.

Spread vegan butter on one side of each slice of sourdough bread.

Place two slices of bread in the pan, buttered-side down.

On each slice of bread, lay down 2 slices of vegan mozzarella, followed by a portion of the caramelized onions, and then another 2 slices of vegan mozzarella.

Top with the remaining slices of bread, buttered-side up.

Cook the sandwiches for about 4 minutes or until golden brown. Then flip and cook for an additional 4 minutes or until the other side is golden brown and the vegan mozzarella cheese has melted. If the cheese isn't fully melted, you can cover the pan for a minute or two to help it along.

Remove from the heat, cut in half, and serve immediately.

Repeat with remaining ingredients if more than one sandwich is desired.
