More Great Sandwiches
In a large skillet, cook the sliced chorizo over moderately high heat, stirring occasionally, until lightly browned, about 3 minutes. Drain the chorizo on paper towels and wipe out the skillet.
Butter the bread on 1 side and turn 4 slices buttered side down on a work surface. Top with Pepper Jack, chorizo, pickled jalapeños and Havarti. Close the sandwiches with the remaining bread slices, turning the buttered side up.
Preheat 2 large skillets. Add the sandwiches and cook over moderate heat, turning once, until the bread is golden and crisp, about 8 minutes. Cut the sandwiches in half and serve.
