In a medium bowl, mix the Hellmann's® or Best Foods® Real Mayonnaise, cream cheese, cheddar cheese, Monterey Jack cheese, green onions and cayenne pepper. Transfer mixture to a shallow baking dish, such as a 9-inch pie plate. Top the mixture with the cracker crumbs.
Bake until heated through, about 15 minutes. Remove from oven and top with bacon. Serve with corn chips, crackers or bagel chips.
