Preheat the oven to high broil.

Chop the bottoms off of the brussel sprouts and then slice thinly, lengthwise. Set aside.

Place a large skillet over medium heat and place in the bacon slices. Cook the bacon until crispy and transfer to a paper towel lined plate. Drain the skillet of all bacon grease except 1 tbsp.

To the same skillet, add in the garlic, cook for 30 seconds and then add in the red pepper flakes and onions. Cook the onions for about 2 minutes and then add in the brussel sprouts. Cook the brussel sprouts for about 3 minutes, tossing frequently and then add in the potato noodles and crumble in the bacon.

Let the potato noodles cook for about 2 minutes, tossing frequently. Then, cover the skillet with a lid and let sit cooking for 3 minutes. Uncover, stir and cook another 3 minutes or until noodles are fully cooked and slightly browned.

Pour the contents of the skillet into a casserole dish in an even layer and serve! When serving, cut into sections first to cut up the noodles. Optional: Sprinkle cheddar cheese on top and broil for 2-3 minutes or until cheese melts into the casserole. Then, cut into sections and serve!
