Heat olive oil in a large pot over medium heat. Add onion and garlic and sauté until the onions begin to turn translucent; lower heat if browning starts to occur.
Add broth. Chickpeas should be just covered with liquid. If level is shy, add some water so the chickpeas are just covered. Bring to a simmer, then lower heat to low and gently simmer for 45 minutes.
Season again, to taste, with salt and pepper. Serve hot – ladle into bowls and eat with Greek Yogurt, Pita Chips, chopped tomatoes, cilantro, or any other toppings you like!
