How to Make It
In a bowl, stir the couscous with 3/4 cup of boiling water. Cover with a lid and steam for 5 minutes. Fluff with a fork.
Meanwhile, in a nonstick skillet, heat 2 tablespoons of the oil. Add the shrimp and crushed red pepper and cook over moderately high heat until golden, 2 to 3 minutes; transfer to a plate. Add the butter to the skillet. Add the beans, capers and lemon juice and cook, stirring, for 2 minutes.
Fold the bean mixture, parsley and remaining 1 tablespoon of olive oil into the couscous; season with salt and pepper. Serve topped with the shrimp.
