Cut the white fish in small pieces. Place them in a bowl together with the juice of the 6 limes. Cover with foil and let it set in the fridge for 50 minutes. The fish should turn white.
In the meantime, cut the red pepper, garlic, dates, and parsley in small pieces.
Once the fish is ready, add the red pepper, garlic, dates, red onion, parsley, and chickpeas to the fish. Mix it.
In a bowl, add the greek yoghurt. Top it with the rest of the ingredients. Finish it with olive oil.
Dig in with tortilla chips.
