Preheat Oven: Preheat your oven to 375°F (190°C).
Cook Meat: In a large skillet, cook ground beef and hot pork sausage over medium heat until browned and fully cooked. Drain any grease.
Add Seasonings: Stir in garlic salt, oregano, and red pepper flakes. Mix well.
Melt Cheese: Add diced Velveeta cheese to the skillet, stirring over low heat until fully melted and combined with the meat mixture.
Prepare Bread: Arrange slices of cocktail rye bread on a baking sheet. Optionally, toast the bread for 2–3 minutes.
Assemble: Spoon the cheesy meat mixture onto each bread slice, spreading evenly.
Bake: Bake for 10–12 minutes or until the topping is bubbly and the bread is slightly crispy.
Serve: Remove from the oven, let cool slightly, and serve warm.
