Layer the lettuce in the bottom of a clear glass 3-quart (3 L) bowl, followed by the carrots, pasta, peas, onion, ham, and cheese. Mix together the mayonnaise, mustard, and fresh herbs. Spread the mayonnaise mixture over the salad and cover with plastic wrap. Chill for 2 hours or overnight. Toss to mix the ingredients thoroughly immediately before serving. Serves 4 to 6.
