How to Make It
Reserve 1/2 cup black-eyed peas. Pulse rice and remaining peas in a food processor 8 times or until coarsely chopped. Transfer to a large bowl; add reserved peas.
Stir together celery, bell pepper, and onion. Heat 2 Tbsp. butter in a large skillet over medium heat. Add half of celery mixture to skillet. Stir in 1 tsp. salt and 1/4 tsp. black pepper. Cook, stirring occasionally, 5 minutes. Stir in turnip greens, and cook, stirring occasionally, 4 minutes or until wilted; stir into pea mixture.
Stir eggs, 3/4 cup panko, and 1/2 tsp. salt into pea mixture. Using wet hands, shape into 14 balls. Place balls on a baking sheet, 1 inch apart. Flatten each ball to form a 3/4-inch-thick patty, and place in freezer.
Heat remaining 2 Tbsp. butter in a medium saucepan over medium-high heat. Add remaining celery mixture, 1 tsp. salt, and 1/4 tsp. black pepper. Cook, stirring occasionally, 5 minutes or until softened. Add garlic and jalapeño pepper, and cook, stirring occasionally, 1 minute. Stir in wine; cook, stirring occasionally, 3 minutes or until reduced to 1/4 cup. Stir in tomatoes and Creole seasoning. Reduce heat to low; simmer 8 minutes.
