Hot-Smoked Mackerel Salad with Avocado and Puy Lentils
A vibrant, protein-rich salad that transforms hot-smoked mackerel into an elegant light meal. The smoky, flaky fish pairs beautifully with creamy avocado, tender puy lentils, and peppery lamb's lettuce, creating layers of texture and flavor in every bite. Fresh cherry tomatoes and bright lemon juice cut through the richness of the oil and fish, while chives add subtle onion notes. This salad suits anyone seeking a quick, nutrient-dense lunch or dinner that feels restaurant-quality yet requires minimal cooking. Serve it as a main course for two or a sophisticated starter for four. What sets this version apart is the balance of warm, smoky protein against cool, crisp vegetables and the sophisticated pairing of mackerel with lentils rather than heavy grains. Ready in under 15 minutes, it's perfect for busy weekdays or casual entertaining.

Tips
Squeeze lemon juice on avocado immediately after slicing to prevent oxidation and browning. Keep the lemon in the dressing as well for brightness and to balance the richness of the fish and oil.
Use a gentle hand when tossing to keep the mackerel in chunks and the avocado intact. Broken fish loses its smoky presentation and mushy avocado muddies the delicate textures.
Serve the salad as soon as it's dressed. Lentils absorb liquid quickly and the leaves will wilt if left sitting more than a few minutes.
Good to Know
Store components separately in airtight containers for up to 3 days. Keep lentils and tomatoes in the fridge; avocado and lettuce will wilt if stored with dressing. Dress just before serving.
Prepare all components (break mackerel, slice avocado, halve tomatoes, snip chives) and store separately up to 2 hours ahead. Make dressing up to 6 hours ahead and store in a jar. Assemble and dress only when ready to serve.
Serve chilled or at room temperature as a main course for two or a starter for four. Pair with crusty bread, a crisp white wine like Sauvignon Blanc, or serve alongside grain bowls for a lighter version.
Common Mistakes
Add avocado too early to avoid browning and sogginess from prolonged contact with acidic dressing.
Under-season the dressing to avoid bland salad; the pinch of sugar balances acidity and the lemon must shine.
Over-toss the salad to avoid breaking the mackerel into dust and crushing the avocado into paste.

FAQ
Can I make this salad ahead of time?
Prepare components separately up to 2 hours ahead, but assemble and dress just before serving. Avocado browns quickly and lettuce wilts when exposed to dressing. The mackerel and lentils stay fresh in the fridge for up to 3 days stored separately.
What if I don't have puy lentils?
Green or brown lentils work well as substitutes in roughly equal quantities. Chickpeas offer a heartier alternative but shift the dish's character. Avoid red lentils as they'll become mushy. Any ready-cooked legume adds protein; adjust seasoning as needed.
Can I use cold-smoked mackerel instead?
Yes, but cold-smoked is more delicate with a silky texture and less pronounced smoke. The salad will feel lighter and more refined. Hot-smoked has a bolder, warmer profile. Both work well; choose based on your preference for intensity and texture.
