How to Make It
Coarsely chop the broccoli into florets and place them in a large bowl.
In a food processor, combine the olives and green onions. Pulse together until finely chopped.
Fold the olive mixture into the broccoli.
In a separate bowl, mix together the garlic, mayonnaise, lemon juice, pepper, and sugar.
Combine the broccoli salad and lemon-garlic dressing and mix together well. Season with salt and pepper, then refrigerate for at least 2 hours or overnight before serving.
