1 unsliced loaf sourdough bread
12-16 ounces Monterey Jack cheese, shredded
1/2 cup butter, melted
1/2 tsp ground mustard
2 teaspoons poppy seeds
2 teaspoon onion flakes
1 teaspoon Worcestershire sauce
1/2 cup finely diced green onion
Preheat oven to 350 degrees.
Carefully, cut the bread in a crisscross fashion, lengthwise and width-wise without cutting through the bottom crust.
Place bread on a foil-lined baking sheet and stuff cheese between cuts.
Combine butter, ground mustard, poppy seeds, onion flakes, and Worcestershire sauce.
Drizzle over bread, coating the crust and any exposed cut edges of the bread.
Wrap loaf completely in foil and bake at 350 degrees for 15 minutes.
Unwrap and bake 10 more minutes, or until cheese is melted.
