Heat the olive oil in a medium saucepan over medium-high heat. Add the pearl couscous and toast, stirring frequently, until golden brown, about 3 to 4 minutes.
Add the chicken broth and kosher salt to the saucepan. Bring to a boil, then reduce the heat to low. Cover and simmer for 10 to 12 minutes, or until the couscous is tender and the liquid is absorbed.
