For the cashew vinaigrette:
- In a medium skillet, heat 1/4 cup of the olive oil over medium heat. Add the cashews and cook, stirring, until golden brown, 5 to 7 minutes. Stir in the remaining 1/2 cup olive oil and the chile and stir to combine. Scrape the contents of the skillet into a small bowl and stir in the vinegar, lemon juice, salt, and pepper.
For serving:
- Combine all the herbs in a small bowl. Add about half of the herbs to the vinaigrette. Place the lettuce halves, cut side up, on four serving plates. Spoon some of the vinaigrette over each lettuce half. Top each salad with some of the radishes and olives, sprinkle with the remaining herbs, and finish each salad with some freshly cracked black pepper. Serve.
