Chickpea Tuna Salad is a fresh and flavorful salad with a tangy Dijon dressing and crisp veggies. It's great as a side dish just as it is, add lettuce to make it a main dish salad, or use it as a filling for sandwiches and wraps.
Drain the tuna and break it into large pieces. Combine it with chickpeas, capers, garlic, celery, bell pepper, and shallot in a large bowl.
In a small dish, whisk the lemon juice, olive oil, mustard, salt, pepper, and red pepper flakes. Pour the dressing over the tuna mixture and gently stir.
Let the salad sit for 5 minutes before serving it.
