Cucumber Salad

Fresh avocados, cucumbers, tomatoes, and onions topped with feta cheese and tossed with a homemade dressing made with balsamic vinegar - it's the perfect healthy side dish to any meal!

This Avocado Cucumber Tomato Salad is topped with feta cheese and is the perfect side dish to any meal!

Light and fresh, this simple salad pairs perfectly with grilled chicken (like our Rosemary Ranch Chicken), pork (try this Smoky Grilled Pork Chop recipe) or fish (this Parmesan Crusted Tilapia is delicious!).

How to make Avocado Cucumber Tomato salad

  • In a bowl, gently toss cucumbers, tomatoes, and onions together.
  • Add avocado and feta cheese, mixing carefully.
  • In a separate bowl, mix together homemade dressing (vinegar, olive oil, salt and pepper).
  • Pour dressing over salad and toss together.
  • Serve and enjoy!

How to keep your avocado from browning

If you are not serving this dish immediately, do not add the avocado until right before serving so that the avocado does not turn brown.

However, one way to keep the avocado from turning brown is to cut the avocado into cubes and then toss the avocado pieces with a little bit of fresh lemon juice.

I would recommend using fresh lemon juice because of the flavor (the bottled lemon juice can sometimes have a tart or bitter aftertaste, which doesn’t compliment this salad).

What salad dressing goes with avocado?

The dressing used in this salad is light, fresh, and so easy to make!

Depending on how much fresh produce you use, you can double this recipe as needed.

Simply mix together 1 part balsamic vinegar to 2 parts olive oil. Add salt and pepper to taste. So simple, but it compliments the fresh produce in this salad perfectly!

What cucumbers should be used in this salad?

Any kind of cucumber will work for this salad, but one of my favorite varieties is an English cucumber. These cucumbers are long and skinny and slightly sweeter than regular cucumbers.

They are perfect for salads because of their thinner skin (no need to peel the skin of these cucumbers!) and smaller seeds.

Substitutes for Feta Cheese

Don’t like feta cheese? No worries! Try one of these substitutes instead:

  • Ricotta cheese (crumbly like feta, but less salty)
  • Queso Fresco (this is a Mexican cheese)
  • Goat cheese
  • Fresh mozzarella cheese cut into small pieces
