Place first 9 ingredients in a blender or food processor; process until smooth. Place 2 tablespoons dressing, spinach, and fennel in a large bowl, and toss gently to coat. Arrange 1 1/4 cups of spinach mixture on each of 4 plates, and top each serving with 1/2 cup quartered strawberries and 1 tablespoon feta cheese. Drizzle each serving with 1 1/2 teaspoons dressing.
Delicious! A simple potluck meal if desired, simply combine the blended ingredients with the other ingredients in a large bowl.
