In a large serving bowl, combine the cherry tomatoes, Kalamata olives, feta cheese, capers, and black pepper.
Sprinkle 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 minced garlic during the last minute of cooking.
Transfer the shrimp to the bowl with the tomato mixture.
Pour the vegetable broth into the skillet and bring it to a boil.
Stir in the pearl couscous, cover, reduce heat to medium, and cook for 10–12 minutes until the liquid has been absorbed.
Fluff the couscous with a fork and add it to the shrimp mixture.
Pour in the fresh lemon juice and gently toss everything together until evenly combined. This Mediterranean Couscous with Shrimp is best served warm.
Garnish with chopped fresh parsley before serving.
