Preheat oven to 375 F°. Brown ground beef in a large skillet, over medium-high heat. Drain grease. Add taco seasoning to the ground beef according to pkg directions. Simmer 10 minutes, then remove from heat.

Slice french bread in half lengthwise. Place both halves on a greased large cookie sheet.

Place refried beans into a microwave-safe bowl. Microwave for 1 minute. Stir well and then spread beans evenly over the top of french bread halves. Then top evenly with the cooked ground beef mixture, sprinkle with cheese and then add the tomatoes, black olives and green onion.

Bake 12 to 15 minutes, or until cheese is melted and bubbly. Remove from oven and let stand 5 minutes before slicing and serving.
