Simple Ingredients

This avocado salad is fresh, colorful and loaded with delicious flavor, all using such simple ingredients!

Cucumbers – English cucumbers are longer, thinner, and hold up better than ‘field’ cucumbers, but either will do in this recipe.

Tomatoes – Grape tomatoes come in a variety of colors that will make this recipe pop, but cherry tomatoes fresh from the garden (or farmer’s market) are tasty too!

Avocadoes – Look for firm, heavy avocados, that are just a little bit underripe so they stay firm. Frozen halves can be used once thawed.

Vinaigrette – The simple blend of lemon juice, olive oil, and red wine vinegar is all you need to elevate the flavors of the ingredients. In a pinch for time? Use a bottle of Italian dressing, but start with a small amount to keep the salad balanced with flavor.

Variations – Small mozzarella balls (AKA bocconcini), crumbled feta or blue cheese crumbles add color and tangy flavor to this salad. Other protein additions can be bay shrimp, bacon bits, chia, hemp, or pumpkin seeds. If you don’t have dill, fresh basil, parsley, oregano, or thyme are perfect!

How to Make Cucumber Tomato Avocado Salad

Refreshing, low-carb, and low in calories, this is a recipe to remember!

  1. Cut avocado into cubes and toss in lemon juice (as per the recipe below).
  2. Add remaining ingredients and chill before serving.

Best Avocado Salad Tips

  • If making ahead, prep everything except the avocado. Chop and add the avocado to the salad just before serving.
  • Toss avocado cubes in lemon juice to prevent them from browning.
  • This avocado salad recipe provides lots of room for mixing and matching other fresh keto veggies.
  • Make in small batches for freshness, but it can easily be doubled or tripled if needed!

Serving and Storing Ideas

Avocado tomato salad makes the perfect side dish to many entrees including grilled chicken or shrimp!

Keep leftover tomato avocado salad in a covered container in the refrigerator for up to two days. Drain any liquid from the salad and refresh with salt and pepper before serving again.

Leftovers can be tossed into a Cobb salad or tucked into a low-carb wrap.
