Gather all your ingredients including romaine lettuce, tomatoes, cucumbers, olives, and any protein like salami or chickpeas.

Wash and chop the romaine lettuce into bite-sized pieces. Dice the tomatoes and cucumbers into similar-sized chunks.

In a small bowl, whisk together olive oil, red wine vinegar, Dijon mustard, minced garlic, salt, and pepper to create the dressing.

In a large mixing bowl, combine all chopped vegetables, olives, and any proteins. Drizzle the dressing over the salad and toss to combine.
