Blanch the vegetables. Bring a pot of salted water to a boil. Add the cut carrots and green beans to the boiling water and cook for 4 to 5 minutes, or until the veggies are just tender. Drain.
Cook the bacon. In the meantime, set a cast iron skillet over medium-high heat and heat it up until hot. Add the diced bacon to the skillet and cook for 4 to 5 minutes, or until just starting to crisp up.
Add onions and apples. Stir in the diced onions and cook for 3 minutes, or until softened. Stir in the apple slices, hot sauce, and brown sugar; cover and cook for 4 minutes.
Stir in the carrots and beans. Add the carrots and green beans to the skillet; stir and cover, and continue to cook for 2 more minutes, or until heated through and tender.
Finish and serve. Season with salt and pepper; taste for salt and adjust accordingly. Remove from heat and serve.
