HEAT oven to 375°F. Cook bacon in large skillet over medium heat until almost crisp. Drain all but 1 teaspoon bacon drippings. Add stir-fry vegetables and cook until thawed, about 5 minutes, stirring occasionally.
MIX brewed coffee, barbecue sauce, brown sugar and soy sauce in large bowl. Stir in chili beans, kidney beans, cannellini beans, black beans and bacon mixture. Spoon into a 3-quart shallow casserole dish coated with no-stick cooking spray.
COVER and bake 30 minutes. Uncover and stir. Bake, uncovered, an additional 15 minutes or until hot and bubbly.
