Combine pasta, water and bouillon in large saucepan. Bring to a boil. Cook, stirring frequently, for 8 to 10 minutes or until pasta is tender and broth has reduced to about 1/2 cup; do not drain. Reduce heat to low; add pesto.
Cook, stirring frequently, until sauce has reduced slightly. Stir in tomatoes, broccoli and beans. Cook, stirring occasionally, until heated through. Sprinkle with cheese before serving. Season with ground black pepper, if desired.
