1. In a large glass or stainless-steel bowl, whisk together the vinegar, Dijon mustard, salt, and 1/4 teaspoon black pepper. Add the 1/3 cup oil slowly, whisking.
2. Heat the broiler. Put the baguette slices on a baking sheet and brush the tops with the remaining 1 1/2 tablespoons oil. Broil until lightly browned, about 2 minutes. Remove the baking sheet from the oven. Turn the slices over and top each one with a slice of goat cheese. Broil until the cheese is soft and warm, about 2 minutes. Sprinkle a little pepper over each croûte.
3. Meanwhile, toss the spinach and radicchio into the dressing. Put the salad on plates. Top with the trout and the goat-cheese croûtes.
Variations:: · Use romaine lettuce instead of spinach.: · Add a handful of frisée to the spinach and radicchio.
Wine Recommendation: France's Chavignol is world renowned for both its Sancerre, made from sauvignon blanc, and its mouthwatering goat cheese. It's no accident that they are splendid together. Try a Sancerre here for the same delicious effect.
