In a large skillet melt the rendered bacon fat on high heat.
Then place the trimmed green beans into the skillet, give it a good mix so that the bacon fat is coated on the green beans. Reduce the heat to medium-high then mix in the bell pepper/onion mix (see notes below), salt, and black pepper. Mix well and then add the ½ cup of chicken broth. Place a lid on the skillet and let cook for 10 minutes. Mix half way through the cooking process and place the lid back on the skillet (add more chicken broth if it's starting to get dry and looks like the green beans could burn).
Remove the lid from the skillet and the pan from the heat as soon as the green beans are done cooking. Mix the green beans one last time and then serve.
