INGREDIENTS
For the vinaigrette:
1/3 cup white wine vinegar
1 clove garlic, minced
1 1/2 teaspoon Dijon mustard
3/4 cup olive oil
Salt and freshly ground pepper
For the salad:
3 large eggs
3/4 pound fingerling potatoes
6 ounces haricot verts or green beans and asparagus
2 (5-ounce) can tuna packed in oil, drained (see Recipe Note)
3 medium plum tomatoes, quartered or 18 grape tomatoes
hearts of palm or artichokes
3 cups salad greens
1/2 cup Nicoise olives
Anchovy fillets (optional)
INSTRUCTIONS
Make the vinaigrette: In a small bowl, whisk together the vinegar, minced garlic, mustard, salt, and pepper. In a slow, steady stream, pour in the oil, and whisk continuously until the dressing is emulsified.
Cook the eggs: Place the eggs in a small saucepan and cover them by an inch with water. Cook over high heat to bring the water to a boil, then turn off the heat, cover the pan, and let the eggs sit for 10 minutes. Drain the water, and place the eggs in ice water to cool. Once cooled, peel and quarter the eggs.
Cook the potatoes: Place the potatoes in a small saucepan and cover with cold water. Add a generous amount of salt and bring to a boil. Cook until potatoes are tender and can easily be pierced with a knife, about 10 minutes. Remove the potatoes with a slotted spoon and set aside to cool.
Cook the green beans: Return the water to a boil and add the green beans. Cook until bright green and crisp-tender, 3 to 4 minutes. Remove beans with a slotted spoon (or drain through a colander) and set aside.
Dress the greens: Add the salad greens to a large bowl. Drizzle a small amount of vinaigrette around the outside of the bowl, then mix until the greens are fully coated. Divide the greens between two plates.
Slice and dress the potatoes: Once the potatoes are cool enough to handle (but still warm), slice crosswise into 1/2-inch slices. In a small bowl, toss the potatoes with a tablespoon or two of vinaigrette. Transfer the dressed potatoes to the individual plates, arranged in small piles.
Dress each of the remaining ingredients: Continue dressing the remaining ingredients with 1 to 2 tablespoons of vinaigrette each. If your olives were packed in a flavored oil or brine, you can skip tossing them with the vinaigrette.
Assemble the salad: As you finish tossing each ingredient, transfer them to the plates and arrange them in sections, with the tuna in the middle. Serve with any remaining dressing on the side.
