Tuna and Quinoa Power Bowl

Method

Drain the tinned tuna thoroughly — press it gently against the tin's side with a fork to extract excess liquid without pulping the flesh. This matters: residual brine dilutes the dressing and turns the bowl watery within hours. Flake the tuna into a large bowl, breaking it into thumb-sized pieces rather than fine shreds; you want texture and structure, not paste.

Add the cooked quinoa whilst still warm. The grain will absorb the oils and acid more readily at temperature, distributing flavour evenly through the dish. This is your portable-protein scaffold — quinoa's complete amino acid profile complements tuna's methionine-rich muscle. Fold in the spinach raw. Wilting it with heat or warm grain is optional and weakens both colour and nutrient density; the leaves will soften slightly as the salad sits, but retain their bite.

Scatter the halved tomatoes and diced red onion over everything. The raw onion's sulphur compounds will sharpen as they meld with the lemon juice, developing a more integrated bite within the first hour — so don't dice it ahead if you want aggressive sharpness. If you prefer softer onion, dice it twenty minutes before assembly and it'll soften slightly without losing its character.

Dress with the olive oil first, then the lemon juice. Oil creates a barrier that slows oxidation and browning; acid applied after helps it emulsify into the grains rather than bead on the surface. Toss gently but thoroughly — rough handling breaks down the tuna further and bruises the spinach unnecessarily. Season with fleur de sel and cracked black pepper. Taste after five minutes; the tomatoes' liquid will have started releasing, diluting the seasoning slightly, so a second check is worthwhile.

This bowl holds well refrigerated for up to two days, making it ideal for portable-protein meal prep. The quinoa continues to absorb liquid, so store the dressing separately if preparing ahead; dress it just before eating or packing. Serve cold directly from the fridge, or allow fifteen minutes at room temperature so the olive oil's flavour compounds open up properly.
