Pre-heat a grill or grill pan to medium-high. In a medium bowl, combine 3 tablespoons EVOO, the hot sauce, garlic, lemon juice and paprika. Add the shrimp and toss to coat; let marinate for 10 minutes. Thread 4 shrimp and 3 chorizo slices on each of 4 skewers, nestling the sausage in the curve of the shrimp. Grill, turning once, until the shrimp are opaque, 7-8 minutes.
In a medium saucepan, bring the chicken broth, peas, scallions, lemon peel, saffron and remaining 1 tablespoon EVOO to a boil. Stir in the couscous, cover, and turn off the heat; let stand for 5 minutes. Stir in the cilantro, almonds and olives.
Divide the couscous among 4 plates and serve with the shrimp and chorizo.
