Combine salad dressing ingredients in a tightly lidded jar and shake to blend.
Brush lettuces with salad dressing and grill for a few minutes—long enough to make grill marks on each side. Move to a deep platter or bowl. Remove cores and chop into fork-sized pieces.
Top salad with feta, toasted pine nuts, anchovies and/or capers and olives for side salad. For a main dish, add chunky croutons, bacon and soft boiled eggs.
Drizzle with more dressing, toss and pass.
