Preheat oven or grill to 350°F. Mix the soy sauce, water, Allegro Hot & Spicy Marinade, garlic, and brown sugar together until combined.
Add the beans, onions, and sliced smoked sausage to a disposable aluminum pan. Pour the sauce over everything and mix well.
Cover the pan with foil and cook at 350°F for 1 hour. Remove the foil and continue cooking for another 30 minutes, until everything is hot and the sauce has thickened slightly.
