Nachos Dip Bread Bowl

1 (15 ounce) loaf round sour dough
1 (15 ounce) can refried beans or 1/2 pound hamburger
Taco seasoning for meat
1/2 small bottle taco sauce
1 cup grated cheese (any kind)
1 small carton sour cream
1 container refrigerated avocado dip
1 small can black olives, chopped

Slice top off bread and set top aside. Scoop out most of inside, but leave enough so that the "shell" is stable. Layer the following in the hollowed-out bread: beans/hamburger, taco sauce and cheese. Replace top of bread. Wrap in foil. Bake at 350 degrees F for 1 hour and 45 minutes. Unwrap to check if cheese is melted. If not, return it to the oven without the bread lid.
