Mix 2 tablespoons mayonnaise, 3/4 cup shredded extra-sharp cheddar and 1 tablespoon pickled jalapeno brine; season with salt and pepper. Broil 4 slices sourdough bread on a baking sheet until golden, then flip and spread with the cheese mixture. Top with chopped pickled jalapenos and a dash of paprika. Broil until the cheese is melted and bubbly, then cut each slice in half.
