Bring a small pan of lightly salted water to a boil. Blanch the sliced garlic for about 3 minutes, and drain. Set aside.
In a small bowl, whisk together the lemon juice, orange juice, salt, and pepper. Drizzle in the olive oil in a slow, thin stream, whisking all the time, until emulsified. Stir in the minced chiles.
Place washed and dried greens in a bowl, add the slivered garlic and the dressing, and toss to coat evenly. Place a mound of greens on each plate.
Note: To pickle chipotle peppers, combine 6 peppers that have been stemmed and, if desired, seeded with 2 cups of red wine vinegar in a small non reactive saucepan. Bring to a boil, then reduce the heat so the vinegar is simmering. Cook, covered, for 5 minutes. Set aside to cool, then store in a glass jar in the refrigerator for up to 3 months.
