Warm sausage on the grill. Brush sausage rolls with melted butter and grill lightly.
Combine cream cheese, sour cream, crab seasoning, Worcestershire sauce, lemon juice and hot sauce. Once mixed gently fold in crab meat - careful to not over mix and break crab meat chunks up too much.
Place sausage in grilled roll, top sausage with crabmeat topping and sprinkle with green onions if desired.
