This is a straightforward no-cook salad built on cooked quinoa, canned tuna, avocado, celery, red onion, and alfalfa sprouts, all tossed in a simple lemon-garlic vinaigrette. It comes together in about 10 minutes once the quinoa is cool, and it delivers a solid 16 grams of protein per serving without much effort. If you need a filling lunch or a quick weeknight dinner that doesn’t require turning on the oven, this is a practical choice.
Before you start
The one thing that will make or break this salad is letting the quinoa cool completely before you add it. Warm quinoa wilts the alfalfa sprouts, turns the avocado mushy, and makes the whole bowl feel heavy instead of fresh. Spread the cooked quinoa on a sheet pan or wide plate — it cools in about 15 minutes that way, much faster than leaving it in the pot. While it cools, drain the tuna thoroughly and press it with a paper towel; excess water from the can will dilute the dressing and make the salad watery at the bottom of the bowl.
Common problems and fixes
- The avocado turns brown quickly: Toss the chopped avocado in a little of the lemon juice from the dressing before combining it with the other ingredients. The acid slows oxidation noticeably, buying you an extra hour or two of good color.
- The dressing slides off instead of coating: Whisk the olive oil into the lemon juice slowly, or shake them together in a small jar until the mixture looks slightly creamy. A loose, separated dressing just pools at the bottom — dress it at the table so everyone gets an even coat rather than pouring it all over in advance.
- The red onion is too sharp: Raw red onion can overpower the other flavors. Soak the chopped onion in cold water for 10 minutes, then drain and pat dry before adding it. The bite softens considerably without losing the crunch.
- The alfalfa sprouts clump or get lost: Add them last, right on top, and toss gently just once or twice. Over-mixing buries them and turns them into a tangled mat throughout the salad.
- The salad tastes flat: Quinoa absorbs seasoning, so taste the finished bowl after combining everything and add another small pinch of salt directly to the salad, not just the dressing. A little extra lemon zest also sharpens the flavor without adding liquid.
Storage and make-ahead
If you want to prep ahead, cook and cool the quinoa up to two days in advance and keep it in an airtight container in the fridge. Chop the celery and onion the night before — both hold well refrigerated. The avocado and alfalfa sprouts should be cut and added the day you’re serving; avocado browns and sprouts go limp if stored once cut. Assembled but undressed salad keeps for about one day in the fridge with plastic wrap pressed directly onto the surface to slow the avocado from browning. Once dressed, plan to eat it within a couple of hours — the quinoa soaks up the vinaigrette and the sprouts soften past the point of being pleasant.

FAQ
Can I use pre-cooked or microwavable quinoa pouches?
Yes, pouches work fine here. Spread the cooked quinoa out to cool before using it, just as you would with freshly made quinoa, since it comes out of the pouch warm.
What kind of canned tuna should I use?
Tuna packed in water is what the recipe calls for, and it keeps the salad from tasting oily. Chunk light or solid white albacore both work — albacore has a firmer texture that flakes into larger pieces if you prefer that.
I can’t find alfalfa sprouts. What can I substitute?
Broccoli sprouts or mung bean sprouts are the closest swap — both add a similar mild crunch. Thinly sliced cucumber is a reasonable alternative if sprouts aren’t available at all, though the texture will be different.
My avocado isn’t ripe yet. Can I still make this?
An underripe avocado won’t mash into the salad the way a ripe one does, and the flavor will be bland. Wait until the avocado gives slightly when you press the skin, or use it as a firm, cubed topping rather than mixing it in.
Is one cup of dry quinoa really the right amount for four servings?
One cup of dry quinoa yields roughly three cups cooked, which is enough to make the salad filling for four people alongside the other ingredients. If you’re serving it as a main dish for hungrier eaters, cooking one and a half cups of dry quinoa gives you more room.
