Season the flour with the salt and black pepper; dredge the pork. Heat the oil in a 12-inch nonstick skillet over medium-high heat. Add pork to skillet and sear 2 to 3 minutes on each side, until golden and no pink remains. Set aside on a plate.
Add the lemon to skillet and cook 1 minute; turn and cook 1 more minute. Add the wine, chicken broth, capers, butter, sugar snap peas and all but 1 tablespoon of the parsley. Simmer, stirring, 3 to 4 minutes, until peas are bright green and tender. Return pork to the skillet to coat with sauce. Top with reserved parsley and serve.
