Method:
Snip the tiny stem end off each fig and cut in half lengthwise. Mix vinegar, brown sugar and cinnamon together in a medium bowl. Add figs and gently toss to coat. Let marinate while you heat a grill (indoor or outdoor).
If necessary, coat your grill with a little olive oil. When ready, grill the figs, reserving all of the marinade in the bowl, for about 2 to 3 minutes per side or until grill marks appear. Do not overcook as the figs will become too mushy. Remove figs to a plate.
To the reserved marinade, add olive oil, lemon juice, mustard, salt and pepper, whisking well to completely incorporate.
Place greens in a large salad bowl. Toss with dressing, then divide among 4 individual serving plates. Place 2 fig halves on each plate of greens and serve.
