1. Mix all dressing ingredients, down to the garlic salt in a medium bowl.
2. Thinly slice tomatoes, onions and peppers.
3. Add veggies to dressing and toss.
4. You can serve now but I prefer to allow it to sit in the fridge for at least and hour or so.
5. The flavors get better the longer it sits.
6. Serve as a side dish or use the veggies on your favorite summertime sandwich.
