For an elegant salad design, dress the lettuce first and then decorate with tomatoes and peppers (capsicums).
I make a tradional western ranch-style dressing with the following ingredients, and never from an over-priced packaged mix:
a dash or two of D.L. Jardine’s Texas Five-Star Ranch Rub (or Lawry’s Seasoning Salt)
A squeeze of lemon and a bit of freshly-ground green or white peppercorn
