Cut ½ inch off the top and bottom of oranges; then, slicing from cut end to cut end, carefully remove the outer white pith. Using a knife, carefully remove each individual segment, leaving no pith or membrane attached.
In a large bowl, combine oranges, greens, cucumber, tomatoes, zucchini, and Buttermilk Vinaigrette, tossing well to coat ingredients. Arrange mixture on a large serving platter (or divide among six serving plates). Place Stuffed Zucchini Flowers on top of greens. Serve immediately.
In a medium bowl, whisk together all ingredients except oils. In a slow, steady stream, pour in olive oil while whisking. Repeat with canola oil. Season with salt and pepper. Makes about 2 cups.
Stuffed Zucchini Flowers
In a medium saute pan over medium heat, add olive oil and butter. When butter begins to foam, add onions and sweat 2 minutes. Add zucchini and garlic and cook 2 to 3 minutes. Add tomatoes, tomato paste, salt, and pepper, and cook 5 minutes. Remove from heat and let cool to room temperature. Once cooled, mix in 3 tablespoons bread crumbs, cheese, balsamic vinegar, anchovy paste (if desired), and basil. Gently spoon mixture into each zucchini flower.
In a small, shallow bowl, whisk together egg and cream. Place 3 cups bread crumbs in a second shallow bowl. Dip each stuffed flower into the egg-cream mixture, allowing excess to drip back into the bowl, then roll in bread crumbs, coating well. In a medium frying pan over medium-high heat, add vegetable oil. Pan-fry flowers on all sides until lightly browned. Remove to paper towels to absorb excess oil. Serve immediately. Yield: 12 pieces
