Combine flour and Creole seasoning in a large zip-top plastic freezer bag. Add steak; seal bag, and shake to evenly coat.
Heat 1 Tbsp. oil in a large skillet or Dutch oven over medium-high heat. Add half of steak, and cook 2 to 3 minutes on each side or until browned; remove from skillet. Repeat procedure with remaining 1 Tbsp. oil and remaining steak. (Do not remove steak.) Return cooked steak to skillet.
Stir in frozen vegetables and next 3 ingredients. Bring to a boil over medium-high heat. Cover, reduce heat, and simmer, stirring occasionally, 1 hour and 15 minutes or until steak is tender. Spoon over Yellow Grits Wedges, and serve immediately.
