In a large cast-iron skillet or saucepan, add the fava beans and 1/2 cup water. Warm over medium-high heat, then season with a little kosher salt and cumin.
When the fava beans are soft, use a potato masher or dinner fork to mash the beans.
Smash the hot peppers and garlic using a mortar and pestle. Add in the juice from one lemon and stir to combine.
Pour the garlic and hot pepper sauce over the fava beans.
Add a generous drizzle of olive oil, then garnish with the chopped parsley.
