Tuna salad deserves more than to be dolloped on dressed greens for lunch. Some pan-fried chickpeas and the crunch from endive improve things tremendously.
5Tbsp. extra-virgin olive oil, divided
115-oz. can chickpeas, rinsed, patted dryKosher salt
1small shallot, finely chopped
1Tbsp. Dijon mustard
1Tbsp. red wine vinegarFreshly ground black pepper
15-oz. can water-packed tuna, drained
3red or other endive, halved crosswise, leaves separated
½cup parsley leaves
2Tbsp. (heaping) sliced pickled chiles
Heat 3 Tbsp. oil in a large skillet over medium-high. Cook chickpeas, tossing occasionally, until crisp and golden brown, 6–8 minutes. Season with salt and let cool.
Whisk shallot, mayonnaise, mustard, and vinegar in a large bowl; season dressing with salt and pepper. Mix in tuna, breaking up with a fork. Add chickpeas, endive, parsley, and pickled chiles. Finely grate zest from lemon over, then squeeze in juice. Pour in remaining 2 Tbsp. oil and toss to combine. Taste and season with more salt if needed.
