Ingredients Needed

Cucumber, avocado, cherry tomatoes, lemon, olive oil, salt and pepper
  • Avocado: Pick soft avocados that are ripe but not mushy. This is what makes the salad so creamy!
  • Cucumber: English cucumber is best to use as it’s skin is thin and tender. If you use a regular cucumber, peel it first.
  • Cherry tomatoes: Fresh, ripe cherry tomatoes or grape tomatoes will give the salad a burst of sweet, juicy flavor.
  • Red onion: This gives the salad so much flavor and a tiny bit. If you are not a fan, you can use a white onion, sweet onion or green onion.
  • Lemon juice: Freshly squeezed lemon juice not bottled.
  • Olive oil: A light tasting olive oil won’t overpower the salad ingredients. I like to use extra virgin olive oil.
  • Salt and pepper

Variations

  • Fresh herbs: Fresh cilantro, parsley or fresh dill will add another layer of herbaceous flavor.
  • Soak the red onion: To take away some of the onions bite, quickly soak the slices in ice water for 10 minutes.
  • Acid: Try lime juice or red wine vinegar instead of lemon juice.
  • Protein: Add some chickpeas (garbanzo beans) for some plant based protein.

  • Evenly sized vegetables: Chop your vegetables into evenly sized pieces to ensure you get a bite of everything in one forkful!
  • Be gently when combining: Using a spoon will help to not mash any of the delicate vegetables.
  • Generously season: Taste it before serving and add more salt, pepper or lemon juice.
  • Serve chilled: This avocado salad tastes best chilled after the flavors have time to meld together. I recommend at least 30 minutes of chill time in the refrigerator.

An English cucumber is long and thin and has a thin, tender skin. Garden cucumbers have thicker skin which often has a bitter taste. If you using a garden variety, peel the skin and deseed it for best results.
