In a medium or large pot, warm 1 tablespoon oil over medium heat. Add the leek and ½ teaspoon salt and cook for about 3 minutes, or until softened, stirring occasionally.
Add the farro and stir it around for a minute or so to toast the grains. Add water, then cover and bring to a boil over high heat, then reduce to low/medium-low to maintain and simmer for 20 minutes (see farro note) or until farro is cooked through. Remove the lid and let it simmer for 5-7 more minutes, or until the water has evaporated (it’s okay if it’s wet, you just don’t want it soupy).
Stir in the figs and let them rest in the warm farro for a minute to hydrate. Stir in the radicchio and/or kale, remaining ½ teaspoon salt, remaining ¼ cup oil, lemon, balsamic, and black pepper and toss to combine.
Serve warm topped with plenty of cheese, nuts, herbs (if using), and some more black pepper.
