In the bottom of a large shallow dish or pan (a cookie sheet with sides also works well for this), spread a thin layer of refried beans.
On top of the refried beans, add a layer of garbanzo beans. Sprinkle the chili powder and cumin powder on top of the beans. Top with a layer of red onion, a layer of black beans, and a layer of jalapenos.
Next, spread a layer of sour cream and then a layer of salsa. Top with shredded cheese. Sprinkle pepper evenly on top of the cheese.
Add a layer of red cabbage, tomatoes, black olives, cilantro, and green onions. Serve with your favorite chips.
