Preheat oven to 350 degrees F.
Place beans in a saucepan, cover with water, and bring to a boil. Add 1 clove crushed garlic, red onion, and 1 tablespoon salt and simmer until tender. Drain excess water and let beans cool.
In a large bowl, combine cooked beans, lemon juice, hot sauce, remaining garlic, onion, remaining salt, pepper, feta, leeks, bell peppers, and bread crumbs. Form mixture into approximately 20 (4-ounce) patties.
Heat oil in a large skillet over high heat. In batches, saute patties until browned on both sides. Transfer to the oven and finish cooking for 10 minutes. Top bean cakes with sauteed vegetables and serve.
