Rice, tuna and corn salad

Tuna and corn rice salad is a packed-lunch classic: 23 g of protein, 75 g of carbs for 478 kcal, no cooking (except the rice). The rice provides carbs, the tuna lean protein, the corn and vegetables colour and fibre. It travels anywhere, preps ahead and fills you up: the ultimate practical balance lunch.

Once cooled, rice forms resistant starch, a fibre that feeds the gut microbiome and slightly smooths blood sugar: rice salad is therefore even more interesting cold. Oil is the main calorie item: portion it to your goal. For more protein, increase the tuna or add hard-boiled eggs or chickpeas.

Cook the rice, rinse it under cold water to cool it fast and stop it clumping, then mix it with the drained tuna, corn and cut vegetables. Season with oil, vinegar, salt and pepper. It keeps 2 days in the fridge and benefits from resting, the rice soaking up the flavours. Perfect for prepping several lunches ahead.

Rice salad is a canvas that takes anything. Keep the rice as the base and rotate the protein: tuna, hard-boiled eggs, diced chicken, turkey ham, shrimp, feta or chickpeas for a vegetarian version. The vegetables follow the season and the fridge — pepper, tomato, cucumber, peas, red onion, olives — for colour and fibre.

The seasoning changes the mood: classic vinaigrette, soy sauce and sesame for an Asian note, lemon and fresh herbs for freshness. The same cold-rice base gives you a different salad every week, always complete and portable. Make a big batch of rice at the start of the week and assemble as the days go.

The first mistake is letting the rice cool slowly on the counter: that is when bacteria multiply fastest. Spread it on a large plate or tray instead, or rinse it under cold water, then get it into the fridge within the hour. The second mistake is overcooking it: rice that is too soft turns gluey once cold and becomes a mush, closer to a cold risotto than to a salad. Count the time printed on the packet minus one minute, and choose a long-grain rice, such as basmati or jasmine, whose grains stay nicely separate. A last splash of cold water at the end of rinsing stops the cooking and removes surface starch.

Third trap: mixing very watery vegetables in too early. Tomato and cucumber release their water and dilute the dressing; add them at the last moment if you are making the salad for the next day, or deseed the tomatoes. The corn and tuna, for their part, cope very well with waiting. Finally, do not drown the tuna in oil: well-drained tuna in water, flaked with a fork, spreads better through the rice and leaves you in control of the calories, since the only fat is the olive oil you measure yourself. Taste before salting: canned tuna and olives already bring salt.

Rice salad is one of the best meal-prep dishes, because it only needs one pan. Cook 450 g of dry rice on Sunday, which gives three 150 g portions, rinse it, let it drain well and divide it between three airtight boxes, in a thin layer so it cools fast. Add the tuna, corn and base seasoning to each box; the fresh raw vegetables are cut in the morning or the night before and slipped into a small separate container so they stay crunchy. Write the prep day on each box so nothing gets forgotten at the back of the fridge.

Think about transport too: a small pot of dressing kept apart stops the rice soaking it up. If you eat at the office without a fridge, slip an ice pack into the bag, because the salad should not sit more than two hours at room temperature. As for goals, this portion covers the essentials of a training-day lunch: simply raise the rice on heavy training days and lower it on rest days. Take the box out ten minutes before eating: the flavours come through better cool than ice-cold.
