1. 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.
2. 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.
