Combine the olive oil, seasoned vinegar, red wine vinegar, sugar, garlic, and sea salt and freshly cracked pepper, to taste. Whisk until evenly combined. Let the vinaigrette sit for 20-30 minutes to allow flavors to mingle.
Place the broccoli florets in a steamer tray that you have placed in a pot of boiling water. Once the water is boiling, place a lid on the pot and steam for 3-4 minutes or until broccoli is fork tender. Remove from the pot of water and steamer immediately. Pour the broccoli into a serving bowl then drizzle it with the vinaigrette and season with sea salt and freshly cracked pepper, to taste. Toss to coat the broccoli evenly. Serve & enjoy.
