In a skillet, over medium-high heat, fry 4 slices of bacon until really crispy.
Remove from the pain; drain the pan leaving in about 2 teaspoons of the bacon fat; toss in the onion.
Sautee for a couple of minutes; add the minced garlic.
Stir and pour in about a cup and a half of chicken broth.
Add the green beans, bacon, Cajun seasoning and cracked pepper, to taste.
Turn heat to medium; cover and cook for 20 minutes.
