Preheat the fryer. Place the sweet potato chips in the hot oil and fry until golden brown, about 3 to 4 minutes, stirring occasionally to prevent the chips from sticking together. In a large heated saute pan, add the bacon and render until crispy, about 6 minutes, stirring occasionally to prevent burning. Add the mushrooms and saute for 2 to 3 minutes or until the mushrooms start to wilt. Add the onions, beans and garlic and continue to saute for 2 minutes. Season the mixture with salt and pepper. Remove the chips from the oil and drain on a paper-lined plate. Season the chips with salt and pepper. In a mixing bowl, toss the sweet potato chips with the mushroom mixture.
