Instead of microwaving cabbage mixture, cook it on top of the stove. Combine cabbage, onions and water in large saucepan. Bring to boil on medium-high heat; simmer on medium-low heat 10 min., stirring occasionally. Drain cabbage; transfer to large bowl. Add dressing and hot sauce; toss to coat. Refrigerate until ready to serve.
Steak can be marinated up to 24 hours before grilling as directed.
