Cut an oval in the top of the load of bread, scooping out the bread in the center and make a "bread boat." Place the bread on a cooking sheet.
In a large bowl, mix the cream cheese, Cheddar, beef, green onions, tomatoes, bell peppers, hot sauce and chili powder until fully combined. Spoon the mixture into the hollow center of the bread loaf. Bake for 30 minutes, until bubbling, and serve warm with corn chips.
