Dice all vegetables...just cut the grape tomatoes in half. Substitute/add any raw vegetable that you prefer (cauliflower, broccoli, etc.) Mix as you add vegetables to get desired color mix - You may want more or less of items!
Put all dressing ingredients in a jar. Shake thoroughly. Pour over salad mix - turn and toss well. Cover and refrigerate (overnight, if possible). Mix before serving. I keep salt/pepper nearby, so others can season to taste. ENJOY! This makes a huge bowl, but does not stay long, when others start dishing it up! Light and goes well in a picnic environment.
