PREHEAT oven to 375°F (190°C). Bake puff pastry patties according to package directions. Remove the centers and set aside.
HEAT a large skillet over medium-high. Add ground beef and cook, breaking apart with a wooden spoon for 6-7 minutes. Add onion, garlic, carrot, and celery. Continue to cook for 3-4 minutes or until the beef is golden brown and the vegetables are tender. Stir in remaining ingredients and bring to a boil. Reduce heat and simmer for 10-15 minutes. Season with salt and pepper to taste.
ASSEMBLE each Sloppy Joe on a serving plate by filling with the meat mixture and topping with the reserved centers.
Tips: Serve with a side salad. Top with shredded cheese if desired.
