25 min — Medium — Mediterranean
Quick pearl barley cooks in under 15 minutes; frozen corn kernels go straight into the pot during the final minute to thaw in the hot water. Drain both, then toss with olive oil, lemon zest and juice, garlic, crushed red pepper, and chopped bell pepper. Flaked tinned mackerel folds in last — its oil adds richness without extra fat. A cup of chopped cilantro or parsley brightens the whole bowl. Four portions, 25 minutes total.
