Ingredients
  

  • 1 lb Roma tomatoes chopped
  • 1 English cucumber Persian, or garden cucumbers, sliced
  • ½ medium red onion thinly sliced
  • 2 avocados diced
  • 2 Tbsp extra virgin olive oil or sunflower oil
  • 2 Tbsp fresh lemon juice (from 1 medium lemon), or lime juice
  • ¼ cup cilantro* chopped
  • 1 tsp sea salt or 3/4 tsp table salt
  • ⅛ tsp black pepper

Instructions
 

  • Prepare the Vegetables – Add the chopped tomatoes, sliced cucumber, red onion, diced avocado, and fresh cilantro to a large salad bowl.
  • Dress the Salad – Drizzle the olive oil and fresh lemon juice over the vegetables, then gently toss everything together until evenly coated.
  • Season and Enjoy – Right before serving, sprinkle with sea salt and black pepper. Give the salad one final gentle toss, taste, and adjust the seasoning if needed before serving.

Notes

Note: Not a fan of cilantro? No problem! Swap it for 2 tablespoons of freshly chopped dill or chives for a different but equally delicious flavor.

Make Ahead

This salad is at its best when served fresh, but you can save time by prepping a few ingredients in advance. Slice the cucumber and onion, chop the tomatoes, and finely chop the cilantro up to a day ahead. Store everything in separate airtight containers in the refrigerator. When you're ready to serve, simply add the avocado, lemon juice, olive oil, salt, and pepper, then toss everything together for the freshest flavor and texture.

Storage Tips

If you have leftovers, store the salad in an airtight container in the refrigerator for up to 1 day. The avocado may brown slightly, and the cucumber and tomatoes will release a bit of liquid as they sit, but the salad will still be fresh, flavorful, and delicious.
