Preheat the oven to 425 degrees Fahrenheit. Line a baking sheet with parchment paper. Place the beans on the baking sheet and toss them with the oil, salt, and pepper. Bake in the oven for 15 minutes, or until they are crisp and tender.
1 ½ lb green beans, ¼ teaspoon EACH: sea salt and pepper, 1 tablespoon olive oil
While the beans are roasting, prepare the panko. Melt the butter in a small frying pan over medium heat. Continue to let it cook, without stirring, until it becomes golden brown, about 3 minutes. Remove the pan from the heat and stir in the panko.
1 tablespoon butter, ¼ cup panko
In a small bowl, whisk the tahini, maple syrup, apple cider vinegar, garlic, and sea salt. Add the water, 1 teaspoon at a time, until it is pourable.
2 tablespoons tahini, 1 tablespoon maple syrup, 1 ½ teaspoons apple cider vinegar, 1 small garlic clove, 2-3 teaspoons cold water, 1 pinch sea salt
Put the beans into a serving bowl then add the panko, mint, and sumac and toss everything together well.
¼ cup mint, 1 teaspoon sumac
Notes
Tahini is found in most grocery stores, near the peanut butter.
