Preheat oven to 350 and grease an 8x4 bread loaf pan.
Roll out pizza dough into a rectangle that's about 16x8 inches in size.
In a small mixing bowl, combine pumpkin, sugar, spices and pecans. Mix until all incorporated.
Brush dough with melted butter and drizzle 1/4 cup of caramel all over the dough.
Spread pumpkin mixture evenly all over the dough.
Cut the dough easily using a pizza cutter, lengthwise, into three long strips. Then cut in width-wise, creating squares. Stack squares and place them side-by-side into the prepared loaf pan. Drizzle some more caramel over the top and place in the oven.
