Preparation

Step 1

Heat oil in a medium pan over low heat. Cook onion until golden brown, about 30 minutes. (Add 1 to 2 tbsp water if onions stick.) Add 1/4 tsp sea salt; set aside. Place a grater over a bowl. Rub cut surfaces of tomatoes across grater. Discard skins. Add remaining 1/4 tsp salt. Spread grated tomato over toasts (about 1 tsp per toast). Top with onion and tuna. Garnish with chives.
