1 unsliced loaf sourdough bread
12-16 ounces Monterey Jack cheese, thinly sliced
1/2 C. butter, melted
1/2 C. finely diced green onion
2 tsp. poppy seeds

Preheat oven to 350 degrees. Cut the bread lengthwise and widthwise without cutting through the bottom crust. This can be a little tricky going the second way but the bread is very forgiving. Place on a foil-lined baking sheet. Insert cheese slices between cuts. Combine butter, onion, and poppy seeds. Drizzle over bread. Wrap in foil; place on a baking sheet. Bake at 350 degrees for 15 minutes. Unwrap the bread and bake 10 more minutes, or until cheese is melted.
