Broiling the goat cheese atop a toasted crouton makes this popular salad more manageable to eat. Instead of sliding off the radicchio, the melted cheese remains on the crouton where it may be portioned out as you wish.
1. Separate the radicchio leaves and rinse them. Drain on absorbent paper and pat dry. Divide among 4 salad plates and arrange in an attractive manner, leaving a space to one side of the plate. Sprinkle with lemon juice and place in the refrigerator.
2. Using a 2-inch biscuit cutter, cut 4 rounds from the bread slices. Toast or broil on both sides until lightly browned. Transfer to a shallow pan. Cut the rounds of goat cheese about ¾-inch thick and place a round of cheese atop each round of toasted bread. Sprinkle the tops of the cheese with thyme and press down gently. Pour enough oil over the cheese to coat the entire surface. Slide under the broiler and heat until the surface of the cheese looks golden and slightly bubbly. Set a crouton with its cheese to the side of each salad plate and serve at once.
