Heat oil in a large skillet over medium-high heat. Add garlic, bell pepper, and onion; sauté 3 minutes or until tender. Stir in flour and Creole seasoning; cook 1 minute, stirring constantly. Reduce heat to medium; add shrimp, broth, and hot sauce. Simmer, uncovered, 5 minutes or until shrimp mixture thickens, stirring occasionally. Serve over hot cooked rice. Sprinkle with parsley before serving, if desired.
