1. Prepare an ice bath; set aside. Bring a medium pot of salted water to a boil. Add fava beans and cook until very tender, 4 to 8 minutes depending on size. Use a slotted spoon to transfer to ice bath until cool. Drain, and if using fresh, squeeze beans from skin.

2. Meanwhile, heat oil in a medium skillet over medium. Add onion, garlic, minced chile, and cumin, and cook until very soft and translucent, about 10 minutes. Let cool slightly and transfer mixture to a food processor.

3. Add beans, cilantro, lime juice, and a pinch of salt to the processor and process until very smooth, adding 1 to 2 tablespoons water if necessary. Spoon dip into a serving bowl and drizzle with oil. Garnish with sliced chile, cilantro, and mint. Serve with vegetables or flatbread.
