Whisk the first 11 ingredients together in a bowl. Heat the 1/4 cup of olive oil in a large skillet over medium-low. Add baguette cubes and cook, turning occasionally, until lightly toasted, about 5 to 6 minutes. (If you do not have a large skillet, use 2 medium-sized ones.) Toss in 1/2 the Parmesan cheese, then remove from the heat. Toss the lettuce, croutons and remaining Parmesan with the dressing. Serve plates of the salad, if desired, with lemon wedges.
