Blend the vinegar, garlic, oregano
, 1 teaspoon of salt, and 1/2 teaspoon black pepper in a blender
until the garlic is finely chopped. With the blender running, slowly blend in the oil.

, bell pepper, olives, and cheese with enough vinaigrette
to coat. Season the salad, to taste, with more salt and black pepper, and serve.
