Grilled Romaine Caesar Salad

Rinse romaine and let dry. Cut into thick chunks; then toss the lettuce pieces in olive oil, salt, and pepper, to taste. Brush a grill pan with additional olive oil and heat a grill pan over medium-high heat. Grill romaine pieces until char marks start to form and lettuce begins to soften, turning occasionally, about 3-4 minutes. Place the grilled greens on a plate, drizzle with dressing, and top with grilled bread croutons, if you like. To make the dressing: Whisk egg yolk, mustard, salt, pepper, and lemon together in a mixing bowl. Slowly stream in oil while whisking continuously, until dressing comes together.
