The combination of flavors of spicy arugula and tender tuna is perfectly set off by pickled onions and olives. Quail eggs add juiciness to the salad, and cherry tomatoes are good in any dish.
Pre-marinate the onion for 15-20 minutes. For the marinade, mix water, wine vinegar and sugar.
Put the arugula in a large salad bowl, cut the cherries in half and add to the arugula.
Add eggs.
Add the olives.
Mash the tuna a little with a fork in a jar and put it in a salad bowl.
Remove the onion from the marinade and put it on top. Season the salad with olive oil, salt and mix a little. If the tuna is fried in oil, reduce the amount of olive oil for dressing. Ready.
