1. Heat a large, wide skillet over medium heat for three minutes. Add oil. Add shallots and sauté until translucent. Stir in garlic; sauté until fragrant and barely golden, one to two minutes. Add green beans and stir to coat in oil. Season with salt and pepper.
2. Cook green beans undisturbed until they start blistering, five to seven minutes. Give them a stir and allow to cook for another five to seven minutes. Repeat process one to two more times until the green beans are blistered in spots and cooked through.
3. Add soy sauce and maple syrup and stir to coat. Cook another three to five minutes for the flavors to meld. Transfer to a serving platter and garnish with arils. Serve warm or at room temperature.
