To make these marinated tomatoes, you will need
1½ pounds Plum Tomatoes, about 6 good sized tomatoes, cut into bite sized pieces
¼ cup White Onions, sliced paper thin, it will be about ¼ of a medium sized onion
¼ teaspoon Garlic, grated of finely minced, it will be about ½ a clove
¼ cup Balsamic Vinegar
2 tablespoons Extra Virgin Olive Oil
1 teaspoon Salt
½ teaspoon Dried Oregano
¼ teaspoon Black Pepper
Prep Work
The prep for these marinated tomatoes is simple. Start with cutting the ends off the tomatoes. Slice them into quarters, then cut each quarter into roughly ½ inch pieces.
Add the tomatoes to a large bowl. Make sure it’s large enough that you can get in there and give everything a good stir without the tomatoes spilling over.
Slice the onion into paper thin slices. I do this by peeling the onion, then cutting it in half. Then, using a sharp knife, shave the slices off the cut end. Cut the thin, long slices in half if desired.
Add the sliced onions to the bowl with the tomatoes.
Wrap the remaining onion tightly with plastic wrap and keep in the refrigerator for another use.
Grate the garlic. The easiest way to do this is to use a citrus zester/grater. If you don’t have one, then mince the garlic as fine as possible.
Make the balsamic vinegar marinade
Add the grated garlic, balsamic vinegar, olive oil, salt, oregano and black pepper to a small jar or other container with a tight fitting lid.
Cover the jar and shake vigorously until the balsamic marinade is well combined.
Finish the balsamic marinated tomatoes
Pour the dressing over the tomatoes and onions. Toss everything together gently until all of the ingredients are coated and combined. Use a rubber spatula if you have one, or a wooden spoon, to prevent the tomatoes from tearing.
Cover the bowl with plastic wrap (or a lid) and allow the tomatoes to marinate in the refrigerator for at least one hour, and up to overnight.
Taste the tomatoes and add salt, if desired. Just as a reference, we didn’t add additional salt to our marinated tomatoes, but salt is a matter of taste.
