I can’t stop thinking about the cucumber tomato avocado salad I made last night. It may seem ridiculously simple, but it was so pretty and delicious I just had to post the “recipe”.

It all started with a trip to the farmer’s market where cucumbers and tomatoes are in their prime. They are meaty and sweet with not too many seeds which is my preference for tomato salads.

The avocado came from my backyard where the avocados have been plentiful all summer but are now starting to slow down so the season might be over. Only one or two drop every couple of days and most of the time they have a big hole gnawed in one side from a hungry opossum or rat that made its way into the tree. Stinkers.

The ones that are salvageable we devour quickly in easy salads like this one. It literally takes 5 minutes (plus a little chopping time) and the flavors are irresistible.

Ingredients

Ripe cherry tomatoes. Choose ones that are firm, but not mushy and the more colorful, the better. Grape tomatoes will work too.
Persian cucumbers. Or English cucumber, basically any thin-skinned variety with little to no seeds.
Ripe avocado. Look for a ripe avocado that gives slightly when pressed but is not too soft.
Red onion. Or sweet vadalia onions or scallions.
Lemon. For squeezing over everything. Lime juice will work too.
Olive oil. Use the best olive oil you have. Extra virgin olive oil is going to have more flavor. I buy California olive oil simply because it is fresher.
Kosher salt. I always use Morton kosher salt unless otherwise noted.
Black pepper. Freshly ground please.
Fresh herbs. I used chive blossoms but cilantro, parsley, or basil would also be good.

How To Make This Recipe

step one

Cut the veggies. Slice the cherry tomatoes in half and the cucumbers into 1/2-inch thick slices. Cut the avocado into chunks or in thick slices, depending on how you like them and how big they are. Thinly slice the red onion.

step two

Arrange on a platter. Place the tomatoes, cucumbers, and red onion on a large plate or platter and toss to combine then spread in an even layer. Stick the avocado slices here and there.

step four

Serve. Enjoy immediately. The avocado will brown if it sits too long, so this is a real make-and-serve type of situation.

Use heirloom tomatoes or Roma tomatoes or any kind of tomatoes that are ripe and fragrant.
