Ingredients

For the Salad

2 ripe avocados, diced

2 medium tomatoes (or 1 cup cherry tomatoes, halved)

½ small red onion, thinly sliced

2 tbsp fresh parsley or cilantro, chopped

Salt and black pepper, to taste

For the Dressing

2 tbsp extra virgin olive oil

1 tbsp fresh lemon juice

½ tsp Dijon mustard

½ tsp honey

½ tsp dried oregano or thyme

Salt and pepper to taste

Instructions

Prepare the ingredients:
Dice the avocados and tomatoes, and thinly slice the onion.

Make the dressing:
In a small bowl, whisk together olive oil, lemon juice, Dijon mustard, honey, oregano, salt, and pepper until smooth and well combined.

Assemble the salad:
In a medium bowl, add avocados, tomatoes, onions, and parsley. Pour the dressing over the top.

Toss gently:
Mix softly using a spoon or spatula so the avocado stays in chunks.

Serve immediately:
Serve fresh at room temperature or slightly chilled.

Optional Add-Ins

Cucumber slices for extra crunch

Feta cheese for a creamy-salty bite

Olives for a true Mediterranean touch

Basil or mint leaves for extra freshness

Tips

Use ripe but firm avocados so they hold their shape.

Soak red onion slices in cold water for 5 minutes to mellow their sharp flavor.

For meal prep, store the dressing separately and toss right before serving.

Frequently Asked Questions 

Q: Can I make this ahead of time?
It’s best eaten fresh, but you can prepare the ingredients ahead and mix just before serving to prevent the avocado from browning.

Q: What goes well with this salad?
It pairs beautifully with grilled chicken, fish, or falafel and makes a great side to any Mediterranean dish.

Q: Can I replace the lemon juice?
Yes! Lime juice works equally well for a slightly brighter flavor.
