Gather your supplies, I like apple cider vinegar and olive oil. You can substitute.
Peel and slice your onions
Slice your tomatoes in half then cut into wedges
Peel cucumbers then slice across into 1/4 inch pieces
Mix tomatoes, cucumbers and onions together in a large mixing bowl. Then add all the other ingredients and mix well.
Place in covered bowl and refrigerate for about 2 hours before serving. Enjoy this easy summer side dish.
