Sauté ground meat and chopped onion together in large skillet over medium heat. Cook until the meat is browned and the onions are soft; about 7-9 minutes.
Add beans and salt and cook another 3-5 minutes, stirring frequently. Remove meat mixture from pan and set aside to cool.
In medium saucepan, combine Sauce Ingredients (e.g., tomato sauce, salt, chili powder, chopped onion and tomatoes). Simmer over low heat for 10 minutes. Cool before proceeding.
In a large salad bowl, layer ½ lettuce, ½ crumbled tortilla chips, ½ meat mixture, ½ sauce, and ½ grated cheese. Repeat, ending with grated cheese. Garnish with tomato wedges, sliced olives, and reserved whole tortilla chips.

Do this by smoothing the sauce down over the meat mixture with a spatula or the back of a large spoon. As with more traditional layered salads, this step keeps the lettuce crisper longer.
