Prosciutto-Chèvre Grilled Cheese

Instructions

1. In small bowl, stir cheeses, onions, lemon juice and pepper until well combined.
2. With serrated knife, trim off ends of bread; cut remaining bread diagonally into 8 long 1/2" thick slices.
3. Evenly spread butter onto 1 side of bread slices. Place 4 bread slices, buttered side down, on work surface. Spread each slice with cheese mixture, then layer with prosciutto, radishes and arugula. Place remaining 4 bread slices, buttered side up, over fillings.
4. Heat griddle or nonstick 12" skillet over medium heat. Cook sandwiches 6-8 minutes or until bread is golden brown and cheese melts, turning once and pressing down occasionally with large spatula. Cut sandwiches diagonally in half to serve.
