Fill and preheat your sous-vide oven to 185°F.
Place the green beans and red pepper in a quart size sous-vide bag.
In a small bowl, combine the olive oil, lemon juice, lemon zest, garlic, coriander, salt, and pepper. Pour the mixture into the bag and shake it to evenly coat the green beans.
Vacuum seal the bag, then submerge it in the water bath for 1 hour.
Remove the bag and empty it in a serving bowl. Garnish with some more fresh coriander and enjoy!
