This was a staple of my childhood. My mom would always make it for us kids and it STILL is a favorite salad dish of mine. It's super easy to make and tailor to your families taste buds and diet needs.
All you need is some tomatoes, cucumbers, white/green onion (if you like it), favorite brand of mayonnaise- or if you are vegan- you can substitute olive oil for the mayo.
I made this afternoon's salad with two medium cucumbers , four roma tomatoes, 1/4 a fresh white onion, a heaping tablespoon of mayo, salt and pepper to taste. You just slice up everything that you want in your salad, stir together everything in a bowl to make a light dressing, and enjoy or chill before eating to let all the flavors blend. DELICIOUS!
