Preheat your oven according to the garlic bread package directions, typically 400°F. Arrange frozen garlic bread slices on a baking sheet and set aside.

In a medium skillet over medium-high heat, add the ground beef. Break it apart with a wooden spoon and cook until fully browned, about 6 to 8 minutes. Drain excess fat and return beef to the skillet.

Add condensed tomato soup, ketchup, Worcestershire sauce, yellow mustard, onion powder, salt, and garlic powder to the beef. Stir well to combine all ingredients.

Bring the mixture to a gentle simmer, then reduce heat to low. Let it cook for 3 to 5 minutes, stirring occasionally, until thickened and flavors meld together.

While the filling simmers, place the baking sheet with garlic bread in the preheated oven. Bake for 5 to 7 minutes until golden and crispy on the edges.

Remove garlic bread from the oven. Spoon approximately ⅓ cup of the beef mixture onto each slice of toasted garlic bread.

Sprinkle about 2 tablespoons of shredded colby jack cheese over each topped slice. Return the baking sheet to the oven for 1 to 2 minutes, just until cheese is melted and gooey.

Remove from oven and let cool for 1 minute before serving. Enjoy immediately while the toast is still crispy.
