Ingredients For Tomato Salad
- Tomatoes - I’ve used large ripe tomatoes that are each cut into 6 thinner wedges. You could use smaller tomatoes such as grape tomatoes, cherry tomatoes, or heirloom tomatoes, cut into quarters.
- Onion - A sweet onion is best for this salad. Cut the raw onions in half-moons. You can also use red onion for a more intense flavor. To make their flavor less strong you can soak the slices in cold water for 15-30 minutes.
- Olive oil - Using good olive oil of the highest quality will make a huge difference to the taste of this onion salad recipe. If you don't have olive oil, you can also use vegetable oil, canola oil or avocado oil.
- Balsamic vinegar - This is the popular choice for this simple salad but you could also use red wine vinegar, simple vinaigrette, or tangy vinaigrette dressing.
- Salt - A teaspoon of salt to taste is all you need. Kosher salt or table salt will do.
- Oregano - Use ½ teaspoon or 1 teaspoon for more flavor. Fresh herbs such as fresh basil or fresh dill would also be great additions to the refreshing side dish. My go-to dried herbs are usually oregano, basil, thyme, or a blend of different Italian seasonings.

Tips
- Since I’ve used large tomatoes, I prefer to slice them into thin wedges but you can cut them in half or in quarters, especially when using smaller tomatoes such as Cherry or Grape tomatoes.
- Using the best quality olive oil will really add to the flavor of this salad. Something like Italian Nocellara extra virgin olive oil is great although you can use whatever quality brand that you enjoy the most.
- To intensify the flavors in this simple salad, allow it to sit for 10-15 minutes.
- Leftover tomato salad can be added to a blender together with other tasty ingredients to make a salsa or you can toss them into a leafy green salad so that nothing goes to waste!id as time goes on.
Storing Leftovers
- To Store: This salad is best when served right away. You can refrigerate it for up to 2 days, however, the flavor is not the freshest on the second day.
- Make ahead: Dressing can be made in advance for 1-2 days but for best results, other ingredients should be cut and combined right before serving.

The overall post is too wordy and long. While the recipe is good, I was discouraged by the length of the post.
Although it may solely be my opinion, all the chat part of the blog could be reduced considerably and it would improve the overall post.

I experimented with a few different varieties of tomatoes for the salad, and heirlooms definitely have the best flavor and texture. Anyone else try mixing tomato types?

This recipe is timely. Just harvested a bunch of tomatoes from my garden and was looking for salad ideas. Will give it a try.
