For the tuna, rinse the fish and pat dry. Drizzle with lemon juice and Worcestershire sauce and season with salt and pepper.
For the vegetables, peel and finely chop the onion. Rinse the chard, cut off the white stalks and cut into strips.
Heat the oil in a saucepan and sauté the onion until soft. Add the chard and sauté briefly. Deglaze with the cider vinegar, pour in the vegetable stock and bring to a boil. Chop the herbs finely and mix into the vegetables. Season with the spices.
