Roasted Green Beans

0 Preheat oven to 425°F. Place a rimmed sheet pan on the countertop, and set aside.
1 Wash green beans and remove the stems. Once trimmed, place in a large bowl.
2 Whisk together the olive oil, balsamic vinegar, mustard, Sriracha, kosher salt, black pepper in a smaller bowl, mixing until incorporated.
3 Pour the wet ingredients on top of the green beans.
4 Toss the green beans with the sauce using tongs until each bean is coated. (You may also do this on the sheet pan, if you don't want to dirty bowls.)
5 Pour the green beans onto the rimmed sheet pan.
6 Bake for 15-18 minutes, or until the green beans are fork tender and slightly charred, then remove from the oven.
7 Sprinkle with the flaky sea salt to finish, then serve immediately.
