In a large serving bowl, combine the cherry tomatoes, Kalamata olives, feta cheese, capers, and black pepper.
Season the shrimp with salt.
Heat olive oil in a large deep skillet over medium-high heat.
Add the shrimp and cook for about 2½ minutes per side until pink and opaque. Stir in the garlic during the final minute of cooking.
Transfer the cooked shrimp to the tomato mixture.
Pour the vegetable broth into the same skillet and bring it to a boil.
Stir in the pearl couscous, cover, reduce the heat to medium, and cook for 10–12 minutes until the broth is absorbed.
Fluff the couscous with a fork and transfer it to the bowl with the shrimp mixture.
Add the lemon juice and gently toss everything together until evenly combined. This Mediterranean Couscous with Shrimp develops even more flavor after sitting for a few minutes.
Garnish with fresh parsley and serve warm.
