Preheat oven to 350°. Cut bread widthwise into 1-in. slices to within 1/2 in. of bottom of loaf. Repeat cuts in opposite direction. Cut cheese into 1/4-in. slices; cut slices into small pieces. Place cheese in cuts.
In a small bowl, mix butter, green onions and poppy seeds; drizzle over bread. Wrap in foil; place on a baking sheet. Bake 15 minutes. Unwrap; bake 10 minutes longer or until cheese is melted.

Savory Party Bread
It's impossible to stop nibbling on warm pieces of this cheesy, oniony bread. The sliced loaf fans out for a fun presentation. It's one of the best savory appetizers I've found. —
Test Kitchen Tips
Take a page from the "magnificent everything bagel" by adding 1 teaspoon each of dried garlic, onion and sesame seeds to the butter mixture.
Get little hands involved by having them place cheese in the bread.
Make it your own by switching up the cheese (we love smoked Gouda and gooey Brie), customizing seasonings, and adding meaty mix-ins. Bacon, diced salami or ham with sliced olives are all great choices.
