ABOUT THIS RECIPEThe balance is in the toppings
This bowl is all about contrast, without any of the components overpowering the others. Quinoa is mild and slightly nutty, broccoli develops a roasted flavor and firm bite when cooked, and tahini makes everything creamy and savory. Lemon and quick-pickled red onion cut through that creaminess. Almonds add a dry, crunchy counterpoint. Toss the components together just before eating, or keep them side by side in the bowl if you want the textures to stand out.
Rinse the quinoa in a fine-mesh sieve before cooking; this washes away any bitter-tasting compounds on the surface. After draining, leave the cooked grains covered in the pan for a few minutes, then fluff them with a fork. This gives you a lighter result than stirring firmly right away. White quinoa is the most neutral choice here, but red quinoa works too; it generally stays a little firmer. Follow the water-to-quinoa ratio on the package if it differs, since cooking times vary by type.
For the broccoli, a large, hot skillet matters more than a complicated marinade. Cut the florets into small, roughly equal pieces and cook them in batches if the pan would otherwise be too crowded. A crowded pan traps steam, so the broccoli is more likely to soften than brown. Let the florets sit undisturbed between turns so they can develop dark spots, but take them off the heat while the stems still have some bite. You can also use a grill pan, though this will give you more pronounced grill marks than the even browning of a regular pan.
Tahini can go from thick to almost liquid as soon as you stir in lemon juice and water. Add the water a little at a time, whisking continuously; this lets you thin the sauce enough to pour without making it watery. If your tahini is very thick or bitter, start with a little less lemon juice and taste before adding the rest. Vinegar, water and a pinch of sugar quickly turn the onion pleasantly tangy; slice it thinly so it has time to absorb the flavor during the short marinating time.
Serve the bowl as a main dish on its own, with extra lemon wedges at the table if you like. For more variety, replace some of the almonds with toasted hazelnuts, or swap the quinoa for bulgur if you want a coarser, wheat-like bite. Store leftover quinoa and broccoli covered in the refrigerator and keep the sauce and onion separate; reheat the grains and broccoli, then serve with the cold toppings. The almonds stay crunchiest if you add them at the very end.
