Preheat the oven to 400°F.

Heat the olive oil in a large skillet over medium heat.

Add the onions, saute for 4-5 minutes, then add the garlic and saute for an additional minute. Remove from the heat and set aside.

Add the pork sausage, ground beef, egg, breadcrumbs, cream cheese, 1 cup cheddar cheese and ½ cup buffalo sauce to a large bowl.

Add the cooked onion and garlic.

Use your hands, or a spatula, to combine everything, then press into a pan.

Place the cheesy meatloaf in the oven and cook for 25 minutes.

Remove from the oven, brush with the additional ¼ cup buffalo sauce and top with the remaining ½ cup cheddar cheese.

Place back into the oven and bake for an additional 15 minutes.

Remove from the oven and let rest for 10 minutes before slicing.
