In a large skillet, cook beef over medium-high heat 5 to 7 minutes, stirring occasionally, until thoroughly cooked; drain grease. Stir in refried beans, salsa, and taco seasoning mix.
Reduce heat to medium. Heat to boiling, stirring occasionally.
In ungreased 2-quart casserole, place 2 cups of the broken tortilla chips.
Top evenly with beef mixture. Sprinkle with bell pepper, onions, 1 cup diced tomato, the cheese, and olives.
Bake uncovered 20 to 30 minutes or until hot and bubbly and cheese is melted.
Top baked casserole with remaining 1/2 cup diced tomato, sliced olives, and remaining 1/2 cup tortilla chips.
