In a large skillet brown the ground beef with onion and green pepper over medium heat, stirring occasionally until meat is completely cooked.
While the meat is browning, spread 1 cup crushed tortilla strips in the bottom of a greased 8 x 8 inch pan.
Heat the refried beans in a small, microwaveable bowl (about 60 seconds) until they are warmed through. Spread the refried beans gently over the top of the tortilla chips.
Once the meat is browned, drain and return to stove. Add 1/2 cup of water and taco seasoning to the meat mixture, and stir until completely combined.
Pour browned meat mixture over the top of the refried beans.
Top with cheddar cheese, and then broil in the oven for 2-4 minutes (until the cheese is melted and starts to bubble).
Top with lettuce, tomatoes, olives and sour cream.
Serve warm.
