I like the use herb scissors with 5 blades to quickly and easily cut the fresh herbs. It even works well when they are still wet from rinsing them.

Since raw onions are often too strong for my taste, I like to use the method outlined in the recipe for Marinated Artichoke Hearts Salad to cut down on their sharpness. However, if you like your onions to have a little kick, you can skip this step.
How to tame a strong onion
Slice the onion crosswise. Separate the slices and place them in a bowl of ice water. Let them soak for at least 15 minutes. Drain and run fresh water over the slices, then proceed with the recipe.
Assembling this salad is very easy. Simply combine all of the ingredients in a bowl, toss well to combine, and enjoy.
This salad goes well with a variety of dishes from rice to pasta to beans. And it's wonderful with some of my favorite vegan gluten-free sourdough bread from Bread SRSLY in San Francisco, which I like to order online and store in my freezer.
Leftover salad can be covered and refrigerated for about 2 days. I personally prefer this salad fresh and at room temperature. This way the tomatoes have the most flavor.
If the onion tastes too strong for your liking, let the onion slices soak for at least 15 minutes in a bowl of ice water. Drain and rinse them under cold water, then proceed with the recipe.
White onions, green onions (scallions), and shallots can all be used raw in salads in place of red onion.
Choose ones that are bright red and have a firm texture. Avoid ones that have burst.
