Cook macaroni in large cooking pot for about 10 minutes or until al dente. Drain and set aside.
While macaroni is cooking, cook bacon slices according to package directions until crisp. Drain bacon on paper towels until cool, then crumble into small pieces. Set aside.
Return macaroni to cooking pot and place on stove over low heat. Add cheese, milk, bacon and beans. Stir mixture occasionally over low heat for about 5 minutes or until cheese is completely melted and mixture is evenly mixed.
Season with salt and pepper and serve immediately. Enjoy!
