Heat 1 Tbsp. olive oil and garlic in a large pan over medium heat, about 2 minutes. When garlic is aromatic, add corn, fava beans, green onion, dill, and parsley (reserving a pinch of green onion, dill and parsley for garnish). Cook for about 4-5 minutes, or until the vegetables are beginning to caramelize. Season with salt and pepper to taste.
