Slice your bread first one way, then the other, making a cross-hatch and being careful not to slice through the bottom of the loaf.
Stuff ¾ a cup of cheese in the cracks of the bread.
In a saucepan, Melt the butter and sauté the garlic. Then add the spinach and artichokes, coating them well in the butter and garlic. Toss in 1/4 cup of the chopped bacon.
Spoon the mixture into the bread over the cheese and into the cracks. Top with the remainder of the cheese and bacon.
Cover with aluminum foil and place on a baking sheet in the middle rack of the oven. Bake covered for 20 minutes and uncovered for a final two minutes. Serve immediately.
