Place the vegetables in a large bowl. Drizzle with a touch of olive oil, salt, and pepper, and add both vinegars; mix well.
A little more salt should be added. Cover with plastic wrap and let the mixture marinate for two hours.
When the mixture is done marinating, place the vegetables and their juices into a heavy-duty blender.
Add one cup of olive oil and puree. Continue adding olive oil until a creamy and smooth texture is formed.
If you want the mixture to be velvety smooth, add additional olive oil if needed, taste, and add additional salt and pepper as needed. Place the mixture in a large bowl.
Drizzle the top with additional olive oil and garnish with raspberries and basil.
