How to Make It
In a large nonstick skillet, heat 2 tablespoons of the olive oil. Whisk in 1/4 teaspoon of the curry powder and add the bread. Toast over moderate heat, stirring frequently, until golden and crisp, about 8 minutes. Transfer the croutons to a plate.
In a bowl, whisk the remaining 3 tablespoons of oil and 1/2 teaspoon of curry powder with the lemon juice; season with salt. Toss gently with the mâche and chives; transfer to plates and top with the croutons.
