Season pork chops with salt, pepper, and garlic salt to taste.

In a large skillet, brown the chops over medium-high heat. Add the onion and mushrooms, and saute for one minute. Pour cream of mushroom soup over chops. Cover skillet, and reduce temperature to medium-low. Simmer 20 to 30 minutes, or until chops are cooked through.

Preheat oven to 400 F (200 C).

To prepare the brussels sprouts, cut off the brown ends and remove any yellow outer leaves.

In a medium bowl, mix them with the oil, salt, and pepper until evenly coated.

Spread them out evenly on a sheet pan and roast for about 30-35 minutes until tender on the inside. Keep an eye on them while cooking and shake the pan every so often so that they brown evenly.

Remove from oven and serve.
