How to make it
Cook the rice according to the packet. While it is still warm, fold through the rice vinegar with the sugar and a pinch of salt, then let it cool completely. Seasoned rice stays pleasant cold instead of drying into a brick — this is the step that makes a cold rice bowl worth eating.
Whisk the yoghurt, lemon zest and juice, mustard, garlic and dill together with plenty of pepper. Taste before you reach for salt: the tuna brings its own.
Dice the cucumber, halve the tomatoes and slice the onions. Drain the corn and the tuna properly — a wet tin is what makes the bowl watery by Wednesday.
Build the bowls with rice, then vegetables, then tuna flaked over the top in large pieces.
Pack the dressing in a separate pot and mix it in only when you eat. Dressing sitting on rice for two days turns it into a wet paste.
Keeps 2 days assembled. If you want it fresher, add the tuna and the cucumber on the morning you eat it and keep the rest packed from the start.

Variations
Mediterranean
Swap the yoghurt dressing for 100 g of pitted black olives, a tablespoon of capers, lemon zest and 2 teaspoons of olive oil per bowl. About 70 kcal and 11 g of fat more, 6 g of protein less, and it keeps better than a dairy dressing.
This version, per serving: ~604 kcal · 46 g protein · 72 g carbs · 14 g fat
Asian-style
Soy-sesame dressing with a teaspoon of sesame oil per bowl instead of lemon-yoghurt, and top with a quarter of an avocado (about 35 g of flesh) — roughly 60 kcal and 9 g of fat more per bowl, and 6 g of protein less.

Coach's tip
This is the bowl for the day with no hob and no microwave: 52 g of protein for 531 kcal, straight out of a tin. Two things worth knowing — tinned fish carries a fair amount of sodium, which is why the dressing gets no added salt; and if you eat tuna more than twice a week, alternate it with the salmon or prawn bowl rather than making it the daily habit.
