How to Make It
Preheat oven to 400°F. Stir together cream cheese, red pepper, oregano, garlic, and 1 cup of the Italian cheese in a small bowl until well combined. Spread cheese mixuture in a 1 1/2-quart baking dish, and bake in preheated oven until heated through and slightly bubbly, 8 to 10 minutes.
Increase oven temperature to broil. Spread marinara evenly on cream cheese mixture, and sprinkle evenly with remaining Italian cheese, chopped Canadian bacon, and diced pineapple. Broil until pineapple is slightly caramelized and dip is bubbly, about 5 minutes. Let stand 5 to 10 minutes. Serve with bagel chips or baguette slices.
