Combine the farro and chicken broth in a medium saucepan. Cook according to package directions. Fluff with a fork and drain, reserving the liquid.
Heat a large nonstick skillet over medium-high heat and coat with cooking spray. Add the sausages and cook, stirring occasionally, until the sausages are starting to brown, 7 to 8 minutes. Transfer the sausages to a bowl.
Heat the olive oil in the same skillet. Add the garlic and cook, stirring constantly, for 15 seconds. Add the tomatoes and cook for 1 minute.
Add ¼ cup plus 2 tablespoons of the reserved farro cooking liquid, cover and reduce the heat to medium. Cook until the tomatoes are softened, about 3 minutes. Press the tomatoes with the back of a wooden spoon so that they burst.
Add 2 additional tablespoons of the reserved cooking liquid and stir in the farro, cooked sausage and arugula.
Transfer the farro to a serving dish and top with the Parmesan cheese.
