How to Make It
Preheat the oven to 400°. In a medium bowl, toss the baguette cubes with 2 teaspoons of the olive oil. Spread the bread on a baking sheet and bake for about 10 minutes, or until nicely browned.
In a large bowl, mix the garlic, mustard, vinegar, salt and pepper together. Stir in the remaining 3 tablespoons olive oil.
Just before serving, add the frisée to the bowl and toss with the dressing. Divide among 4 salad plates and sprinkle the croutons on top.
