Prep: 18 minutes. To remove citrus fruits' bitter white pith, cut the peel away with a sharp knife. This recipe makes more dressing than you'll need; you can refrigerate the extra for up to 5 days.
Combine first 4 ingredients (through honey) in a food processor or blender, or use a handheld immersion blender, and process for 1 minute until the mixture is smooth and creamy.
Combine the remaining ingredients (except the greens) in a large, nonreactive bowl (glass, stainless steel, or glazed ceramic). Toss with half of the dressing to moisten. Serve over field greens.
