Bring vegetable broth to a boil in a small pot—you'll see actual rolling bubbles, not just steam. Pour it over the couscous in a medium bowl, add the olive oil, and immediately cover tightly with plastic wrap or a plate. The trapped heat cooks the grains in exactly four minutes.
While the couscous rests, chop your cucumber, halve the cherry tomatoes, and finely mince the red onion. I prep these into separate piles on my cutting board so I can grab each one without mixing flavors yet. This takes maybe five minutes total.
Roughly chop the parsley and mint together on a cutting board—don't overthink the size. When herbs bruise from over-chopping, they oxidize and turn darker, which is honestly just cosmetic but feels like a small loss.
After four minutes, uncover the couscous carefully because the steam will rise fast and startle you. Fluff the grains with a fork, breaking up any clumps that formed. I press the fork into the sides of the bowl and lift gently rather than stirring.
Pour the lemon juice and remaining olive oil directly onto the warm couscous while it's still steaming. Toss gently to coat—this is crucial because warm couscous actually absorbs the citrus flavor. If you wait until it cools, you're just adding flavor to the surface.
Add the cucumber, tomatoes, red onion, and fresh herbs to the warm couscous. Toss everything together using two spoons or your hands if you don't mind getting them slightly sticky. The warmth helps flavors meld rather than staying separate.
Finally, top with your grilled chicken strips and season with salt and black pepper to taste. I always let each person at the table add their own salt since Mediterranean summer side family members have different preferences about how much they want.
