Ingredients You’ll Need
This recipe uses fresh, simple ingredients that feel like a Mediterranean dream.
- 1/2 cup extra-virgin olive oil
- 3 tablespoons red wine vinegar
- 1 tablespoon Dijon mustard
- 1/2 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
- 1 cup baby potatoes, halved and boiled
- 1 cup fresh green beans, blanched
- 1 cup cherry tomatoes, halved
- 1/2 cup Kalamata olives, pitted
- 2 tablespoons capers, rinsed
- 2 cans (5 oz each) tuna in water, drained
- 4 large hard-boiled eggs, quartered
- 4 cups Bibb lettuce, torn
Step-by-Step Directions
- In a small bowl, whisk together the olive oil, red wine vinegar, Dijon mustard, salt, and pepper.
- Divide the dressing evenly among four 32-ounce wide-mouth mason jars.
- Add the cooked potatoes and blanched green beans as the first layer.
- Add a layer of cherry tomatoes, Kalamata olives, and capers to each jar.
- Distribute the flaked tuna evenly across the jars.
- Add the quartered hard-boiled eggs on top of the tuna.
- Fill the remaining space with the torn Bibb lettuce.
- Seal the jars with airtight lids and refrigerate.
Best Ways to Enjoy It
When you are ready to eat, just shake it vigorously. This coats every single layer in that tangy Dijon dressing. You can also dump it into a large bowl for a restaurant-quality experience.
Pair it with a crusty piece of baguette. A glass of chilled sparkling water makes it feel special. It is the perfect grab-and-go lunch for your busiest days.
Keep It Fresh
These jars will stay fresh for up to four full days. Keep them standing upright in your refrigerator. Do not tip them over until you are ready to eat. This keeps the dressing away from the delicate lettuce. Freshness is guaranteed with this method.
Tips for Best Results
- Use wide-mouth mason jars for easier filling and eating.
- Make sure your potatoes and beans are completely cool.
- Dry your lettuce thoroughly using a salad spinner.
- Use high-quality tuna packed in water for a clean taste.
- Rinse your capers to control the salt levels.
- Layer the sturdiest ingredients at the bottom.
- Do not overfill the jars so you can shake them.
Ways to Switch It Up
- Swap the tuna for grilled salmon or roasted chicken.
- Use feta cheese instead of olives for a different salt kick.
- Try white wine vinegar if you want a milder dressing.
- Add sliced radishes for an extra peppery crunch.
FAQs
Will the lettuce get soggy?
Not if you follow the layering order correctly. The potatoes and beans act as a protective barrier.
Can I use tuna in oil?
Yes, but you might want to reduce the dressing oil slightly. It will be extra rich and delicious.
Go ahead and treat yourself to the best lunch of your week!
