Start start blending with a pulsing blend (turn on a couple seconds, off, then on again). Continue blending until well-blended and pretty smooth. Taste it to see if you want more garlic or olives. Sometimes tomato pieces get caught in the blender blade dome , a light tap on the bottom or the side of the blender cup will release those pieces. If it is really thick, remove the stick blender and stir in the lemon juice with a fork. If it is still pretty loose you can blend in the lemon juice. I usually find the dressing is too thick, so use a fork to stir in the lemon juice with a fork and it makes just the consistency to dress the salads, noodle dishes and drizzled on vegetables.
