Pour lettuce into a big salad bowl. Break up the olives a little with your clean fingers. Scatter the olives and the sliced red peppers around the salad. Add in the grape tomatoes and the pepperoni slices, too. Into a blender, pour the vinegar. Add the olives, herbs, and cheese, the pepper and oil, too. Have the GH (grown-up helper) place the lid on blender and blend the dressing until everything is all chopped up and mixed up together. Pour dressing over the salad and toss it up good.
