In a large bowl, combine the mashed sweet potatoes, whole wheat flour, baking soda, Italian seasoning and salt. Mix until completely combined. With oiled hands, pat the dough into a 12" pizza pan. Bake in the preheated oven for 15-20 minutes, or until lightly browned.
Remove the pizza from the oven evenly spread the pizza sauce over the top. Top with the Jones Dairy Farm Canadian bacon and the diced pineapple. Sprinkle the cheese over the top. Return the pizza to the oven and cook an additional 10-15 minutes, until the cheese is melted and bubbly.
