Preheat oven to broil. Scoop the flesh from the pineapple halves, getting as close to the edge as possible. Discard the tough center and chop the fruit. You should have about 1 1/2 cups chopped pineapple.
In a medium skillet, heat olive oil over medium heat. Cook onions until soft and translucent, about 3-5 minutes. Stir in diced canadian bacon and cook for another 2 minutes. Add chilis, cream cheese, sour cream, 1/2 cup shredded mozzarella and shredded cheddar cheese to the pan. Stir to melt completely. Stir in half of the bacon, 2 tablespoons chopped scallions and 1/2 cup chopped pineapple. Spoon into prepared pineapple halves and top with remaining 1/2 cup mozzarella cheese.
Place pineapples on a baking sheet and broil until dip is bubbling and top is golden, about 5-8 minutes. Garnish with 2 tablespoons scallions, remaining chopped pineapple, remaining bacon and jalapeno slices.
To make pizza chips, heat canola oil in a skillet to 350 degrees on a deep fry thermometer. Unroll pizza dough and cut into 2-inch pieces or triangles. Working in batches, fry dough until golden and crisp, about 2 minutes per side. Drain on a towel-lined plate. Serve on the side of dip.
