A Lunch Bowl That Holds Up Well
This is the tuna salad I make when I want lunch ready in the time it takes to boil a kettle. There is no mayonnaise here. The dressing is a quick whisk of olive oil, red wine vinegar, Dijon mustard and a little minced garlic, and it coats the tuna and avocado without turning them heavy. The avocado does most of the work for creaminess, which is a nice trick because you get that rich, spreadable feel while keeping the bowl bright and sharp.
A food fact worth knowing: avocados do not ripen on the tree, so the ones sold in most shops are picked firm and softened afterward. If yours is still hard, leave it on the counter for a day or two. When it gives slightly under your thumb, it is ready. Dice it just before you toss everything together, and squeeze a little of the vinaigrette over the cut pieces if you need to hold any back for later, since that slows the browning.
Tuna packed in water is the more neutral choice here, and it lets the mustard and herbs come forward. Drain it well, then break it up with a fork so the flakes stay a bit chunky. Keep the cucumber slices in a thick half moon rather than thin rounds so they stay crisp against the soft avocado. Red onion is strong, so if it bites too hard, cover the thin slices in cold water for ten minutes and drain them before adding.
For leftovers, the tuna mixture keeps in a sealed container in the fridge for a day. The cucumber will soften and release a little water, so I drink the juices off the bottom of the bowl or simply spoon the salad onto fresh greens. Do not store it on the greens themselves, or they will wilt by lunchtime.
If you want something more filling on the side, a slice of toast or a bowl of soup works well. For a warm pairing, the Golden Roasted Cauliflower Mash with Garlic sits nicely next to it on a plate. If you are packing lunch for later in the week, the Crunchy Broccoli Slaw with Tangy Yogurt Dressing travels well in its own container and has a similar tangy note. And if you like a bean-based option for another day, the Chickpea Avocado Salad with Feta follows the same easy method.
