This tuna salad skips the mayo-heavy route entirely. Instead, it layers canned tuna, lentils, chickpeas, spinach, baby beetroot, and dairy-free cheese into four ready-to-go portions in about ten minutes flat. If you need lunches sorted for the week with almost no cooking, this is a genuinely useful recipe.
The technique that matters
The only real technique here is how you layer the components. Spinach goes in first as the base, then the drained lentils and chickpeas go on top โ not mixed in โ so the leaves donโt get crushed under the weight and turn soggy before youโre ready to eat. Drain the lentils and chickpeas thoroughly; any residual liquid pools at the bottom of the container and wilts the spinach fast. Pat them with a paper towel if theyโre still wet after rinsing. Add the olive oil and seasoning last, and keep the dressing at the table โ a pre-dressed salad goes limp fast, especially one built on fresh spinach.
Common problems and fixes
- Watery beetroot bleeding into everything: After draining the can, spread the beetroot pieces on a paper towel for a minute before adding them. This stops the purple liquid from soaking into the spinach and tuna.
- Bland overall flavor: Canned tuna, lentils, and chickpeas are all fairly neutral. A squeeze of lemon juice over the top before the olive oil makes a noticeable difference without adding prep time.
- Cheese clumping or sliding off: Grate the Bio Cheese straight from the fridge โ cold dairy-free cheese grates cleaner and sits on top of the salad rather than melting into it.
- Uneven portions: Weigh or measure the lentils and chickpeas once, then divide by eye into containers. Itโs faster than measuring each portion individually and accurate enough for meal prep.
- Tuna breaking up too finely: Drain the tins well, then flake the tuna in larger chunks rather than stirring it in. Bigger pieces hold up better over several days and give the salad more texture.
Keeping leftovers crisp
Store the assembled portions in airtight containers in the fridge. Theyโll hold well for up to three days โ after that the spinach starts to break down noticeably. Keep the olive oil, salt, and pepper separate if possible, adding them right before you eat rather than at assembly. If youโre packing these for work or school, a small container of olive oil on the side takes seconds to pour over and keeps the greens in much better shape than dressing everything the night before. The lentils, chickpeas, and beetroot are sturdy and wonโt suffer from sitting, but the spinach is the variable to watch.

Frequently asked questions
Can I use dried lentils instead of canned?
Yes, but cook and cool them completely before assembling. Warm lentils will wilt the spinach immediately, and youโll need to plan ahead since dried lentils take 20โ30 minutes to cook and then time to cool.
What can I use instead of Bio Cheese if Iโm not dairy-free?
Any firm cheese that grates well works โ a sharp cheddar or a block of feta crumbled over the top both hold up without going rubbery. Avoid soft cheeses like brie; they donโt distribute evenly over a cold salad.
Do I need to cook anything for this recipe?
No. Everything comes from tins or a bag, and the prep is purely draining, rinsing, cutting, and portioning. The total time is genuinely ten minutes if your containers are ready.
Can I swap the spinach for a different green?
Kale or rocket both work and actually hold up longer in the fridge than spinach does. If you use kale, massage it briefly with a small amount of olive oil first โ it softens the texture and makes it easier to eat straight from the container.
Is canned tuna in oil or in water better here?
Either works, but tuna in spring water gives you more control over the final flavor since youโre adding your own olive oil. Tuna in oil can make the salad feel heavier, especially if you donโt drain it very well.
Can I freeze the portions for longer storage?
No โ spinach, beetroot, and canned chickpeas all lose their texture badly after freezing and thawing. Stick to the three-day fridge window for the best result.
