Ingredients

Instructions

  • Wash and dry the cucumber, tomato, and parsley.
  • Slice the cucumber into thin rounds, dice the tomato, and chop the onion and parsley.
  • In a small bowl, whisk together the lemon juice, olive oil, garlic, Italian seasoning, salt, and black pepper until well combined. This will help coat the ingredients evenly and enhance the flavor.
  • In a large mixing bowl, add the cucumbers, tomatoes, onion, and parsley. Pour the dressing over the top and toss everything together so the veggies get evenly coated.
  • Gently fold in the avocado, being careful not to mash it. Serve immediately, or chill for 15–30 minutes to let the flavors meld together.
  • Tip: If making ahead, wait to add the avocado until just before serving to keep it fresh and prevent browning.

Notes

Cucumber Options: English cucumbers work best since they have thin skin and fewer seeds. If using regular cucumbers, peel them and scoop out some seeds for the best texture.
Avocado Tips: Use a ripe but firm avocado so it holds its shape in the salad. If prepping ahead, wait to add the avocado until right before serving to keep it fresh.
Onion Mellowing Trick: If raw red onion is too strong for your taste, soak the slices in cold water for 10 minutes before adding them to the salad. This helps take the bite out.
Dressing Alternative: If you prefer a creamier salad, mix 1-2 tablespoons of Greek yogurt or sour cream into the dressing.
Make-Ahead Tip: This salad is best eaten fresh but can be stored in the fridge for up to 2 days. Just give it a stir before serving and add a fresh splash of lemon juice if needed.
Storage: Keep leftovers in an airtight container in the fridge. The avocado may brown slightly, but the flavor will still be delicious!
