Prepare the bread bowl first so that it's ready for the dip to be poured in right away.
Cut the top off the bread close to the edge leaving a nice border to hold the dip in. dig out the insides of the bread until it's nice a hallow. Reserve those bread pieces for dipping.
Place the bread on a large serving plater and arrange bread that has been hallowed out around the bread bowl. You can also serve any other left over bread in small baskets or plates around the bread bowl. Now make the dip.
Place the creamed corn, sour cream, sliced ham, chive and cheese in a microwave safe bowl. Mix everything together until fully combined.
Cover the top with a paper towel and heat in the microwave for 2 minutes. Take it out carefully and mix well. Put back in the microwave and heat up for another 2 minutes. Everything should be fully melted by then. If there are still whole pieces of cheese not melted keep heating up in 1 or 30 second intervals.
Pour the just cooked dip into the prepared bread bowl and serve right away.
