In a large skillet over medium heat, add the ground beef, diced onion, and minced garlic. Cook for about 5-7 minutes until the meat is browned and the onions are translucent, stirring occasionally.

Pour in the beef broth and Worcestershire sauce, then stir in the frozen mixed vegetables. Allow the mixture to simmer for 10 minutes.

In a medium bowl, combine the biscuit baking mix and milk. Stir until just blended; don't overmix! Gently fold in the shredded cheddar cheese.

Pour the beef mixture into a greased baking dish, then drop spoonfuls of the biscuit batter on top. Bake in a preheated oven at 375°F for 25-30 minutes.

In a small bowl, combine melted butter with minced garlic. Once out of the oven, brush this garlic butter over the biscuits.
