Green Goddess Broccoli Salad

To prepare dressing: Combine oil and garlic in a small skillet over low heat. Let sizzle for 1 minute, then transfer to a food processor. Add mayonnaise, buttermilk, parsley, chives, tarragon, anchovies, lemon zest, lemon juice, salt, and pepper; process until smooth.

To prepare salad: Bring a large pot of water to a boil. Place a large bowl of ice water beside the stove. Add broccoli florets to the pot; cook just until bright green and tender-crisp, 1 to 2 minutes. Using a slotted spoon, immediately transfer to the ice water. When cool, drain in a colander and pat dry with a clean kitchen towel.

Combine the broccoli florets, broccoli stems, and carrot in a large serving bowl. Add the dressing and toss to coat. Sprinkle with sunflower seeds.
