Ingredients
- 4 ahi tuna steaks, seared and sliced tataki-style
- 4 cups marble potatoes, cooked and halved
- 12 oz green beans, blanched and halved lengthwise
- 2 cups cherry tomatoes, halved
- 1 cup black olives, halved
- 1 bunch watercress
- 1 cup fresh parsley leaves
- 8 caperberries, halved
- 4 eggs, boiled for 7 minutes and halved
- Pink Peruvian salt or sea salt, to taste
- Fresh cracked black pepper
- 1/4 cup fresh lemon juice
- 3/4 cup extra virgin olive oil
- 1 tbsp Dijon mustard
- 1 tsp dried oregano
Instructions
- Step 1: Boil the eggs by adding them to boiling water. Cook for 7 minutes, then transfer immediately to ice water. Once cool, peel and halve the eggs.
- Step 2: Blanch the green beans by boiling them for 2–3 minutes until tender-crisp. Transfer to ice water to stop the cooking, then drain and dry.
- Step 3: Season the tuna steaks with salt and pepper. Heat olive oil in a skillet over high heat and sear the tuna for 30 seconds to 1 minute per side. Let rest before slicing thinly.
- Step 4: In a bowl, whisk together lemon juice, Dijon mustard, dried oregano, and extra virgin olive oil until the dressing emulsifies.
- Step 5: On plates or a large platter, arrange layers of watercress, potatoes, green beans, cherry tomatoes, black olives, parsley, caperberries, and halved eggs.
- Step 6: Top the salad with sliced tuna. Drizzle generously with the lemon dressing, then season with pink Peruvian salt and freshly cracked black pepper to taste.
Tips & Variations
- Use fresh ahi tuna for the best flavor and sear it quickly to keep it tender and rare inside.
- Swap watercress for arugula or baby spinach if preferred.
- Add anchovies or drizzle with a little balsamic glaze for extra depth.
- For a vegetarian version, replace tuna with roasted chickpeas or grilled tofu.
Storage
Store any leftover salad components separately in airtight containers in the refrigerator for up to 2 days. The tuna is best enjoyed fresh but can be kept chilled and eaten within 24 hours. When reheating, avoid warming the tuna; instead, reheat only the potatoes or green beans gently.

FAQs
Can I use canned tuna instead of fresh ahi tuna?
While canned tuna can be used in a pinch, it changes the texture and flavor significantly. Fresh seared ahi tuna offers the best experience for this salad.
How do I keep the green beans bright and crisp?
Blanch the green beans in boiling water for just a few minutes, then plunge them into ice water immediately. This stops cooking and preserves their vibrant color and crunch.

- 1 tsp dried oregano
- Pink Peruvian salt or sea salt, to taste

Instructions
- Boil the Eggs: Place the eggs in boiling water and cook for exactly 7 minutes to achieve a slightly soft but set yolk. Immediately transfer the eggs to a bowl of ice water to stop cooking. Once cool, peel the eggs carefully and cut each in half.
- Blanch Green Beans: Boil green beans in a pot of salted water for 2 to 3 minutes until just tender-crisp. Quickly plunge them into ice water to retain their vibrant color and crispness. Drain well and pat dry.
- Sear the Tuna: Season ahi tuna steaks with salt and freshly cracked black pepper. Heat olive oil in a skillet over high heat. Sear each steak for 30 seconds up to 1 minute per side, aiming for a rare center. Remove from heat and let the tuna rest before slicing thinly tataki-style.
- Make the Dressing: In a small bowl, whisk together fresh lemon juice, Dijon mustard, dried oregano, and extra virgin olive oil until the mixture is thoroughly emulsified and smooth.
- Assemble the Salad: On individual plates or a large platter, arrange a bed of watercress. Neatly layer cooked marble potatoes, blanched green beans, halved cherry tomatoes, black olives, parsley leaves, and halved caperberries. Add the boiled egg halves throughout.
- Finish and Serve: Place the sliced seared tuna atop the assembled salad. Drizzle generously with the prepared lemon-mustard dressing. Season with additional pink Peruvian salt and freshly cracked black pepper to taste. Serve immediately for best flavor and texture.
Notes

- Use fresh ahi tuna for the best flavor and texture; avoid overcooking to maintain a tender, rare center.
- This salad is best served immediately after assembling to enjoy optimal freshness.
- Pink Peruvian salt adds a subtle, unique mineral flavor but can be substituted with sea salt.
