Cook the pasta according to the package directions. Drain.
Heat the oil in a large skillet over medium heat. Add the garlic and cook for 2 minutes, stirring occasionally.
Add the pasta, peas, pork, radicchio, chicken broth, ¼ teaspoon salt, and ⅛ teaspoon pepper.
Cook until the liquid is absorbed and the meat and vegetables are heated through, about 5 minutes.
Toss with lemon juice and more salt to taste. Top with the basil.
