In a mixing bowl, combine ground beef, blue cheese, green onions, seasoning salt, and Worcestershire sauce using your hands.

Roll the mixture into 24 meatballs, each about 1 1/2 inches in diameter.

Melt butter in a large skillet over medium-high heat.

Brown the meatballs in the skillet, working in two batches if necessary to avoid overcrowding.

Return all meatballs to the skillet.

Cover the skillet, reduce heat to low, and cook for 5-7 minutes, or until the meatballs are cooked through.

Transfer the cooked meatballs to a paper towel-lined plate to drain excess grease.

Pour salt, black pepper, and flour into the drippings remaining in the skillet.

Stir briefly until the flour browns slightly.

Add half-and-half cream to the skillet, stirring constantly while increasing the heat to medium-high.

Cook until the sauce is slightly thickened, about 2-3 minutes.

Place the meatballs on a serving platter or in a slow cooker to keep warm.

Spoon the creamy blue cheese sauce over the meatballs.

Garnish with chopped fresh parsley.

Serve the saucy blue cheese meatballs over noodles or rice.

Consider adding steamed sugar snaps or green beans as a side dish.
