Ingredients

  • 1 large head romaine or crisp lettuce, chopped (about 8 cups, 300-350g)
  • 2 cans tuna in water, drained (about 8 oz total, 2 x 120g drained)
  • 1 cup corn kernels, drained (165g)
  • About 7 oz feta cheese, crumbled (200g)
  • 1 small onion, very thinly sliced (about 70g)

Vinaigrette

  • 2 tbsp red wine vinegar (30ml)
  • 1 tsp Dijon mustard
  • 1 tsp dried oregano

How to Prepare

  1. Make the vinaigrette: In a small jar or bowl, whisk olive oil, vinegar, Dijon, oregano, salt, and pepper until emulsified.
  2. Prep the salad: Add chopped lettuce to a large bowl. Scatter over corn, sliced onion, drained tuna (flaked), and sprinkle the crumbled feta on top.
  3. Toss and serve: Drizzle with the vinaigrette and toss gently to coat. Serve immediately.
