3 cups (426 g) sauerkraut, drained and heated, with a pinch of black pepper
1 tomato, thinly sliced
Instructions
To make the spread
Combine all the ingredients except the relish in a blender. Blend until smooth. Stir in the relish. Let sit at least 30 minutes to meld. Store covered airtight in the refrigerator until using.
To make the seitan
Combine all the ingredients in a 9 x 13-inch (23 x 33 cm) pan. Toss to coat. To cook, heat the oil in a large skillet over medium-high heat. Transfer the seitan to the skillet and cook 4 to 5 minutes, stirring occasionally, until lightly browned.
To make the sandwich
Preheat a panini press fitted with the smooth plates to high. Butter the outsides of the bread. Spread the inside of each piece of bread with a tablespoon (14 g) of spread. Divide the seitan evenly among the four sandwiches. Top with the sauerkraut and tomato slices. Put the tops on the sandwiches and grill with the press open 4 to 5 minutes, or until golden. Carefully turn over to cook the second side, 3 to 4 minutes.
