Preheat oven to 350 degrees. Prepare a 9x13 casserole dish with nonstick cooking spray.

In a large skillet over medium-high heat, brown ground chuck, ground sausage, and onion until the meats are browned and crumbled. Drain well. Mix with garlic and place in an even layer in the bottom of the casserole dish.

Whisk together cream cheese, eggs, and heavy cream. Pour mixture over meat layer.

Add pizza sauce over the layer of meats and eggs.

Over the pizza sauce, add the vegetables and canadian bacon. Top with cheese and pepperoni.

Bake for 45 minutes or until the center is set and the cheese is melted.
