Adjust oven rack to lower-middle position; heat oven to 350 degrees. Season chicken thighs with salt and pepper. Heat oil in nonreactive Dutch oven over medium-high heat until shimmering but not smoking; add chicken thighs skin-side down and cook without moving them until skin is crisped and well browned, 10 to 12 minutes. Using tongs, turn chicken pieces and brown on second side, about 5 minutes longer; transfer thighs to large plate.

Pour off all but 1 teaspoon fat from pot. Add onion and tomato paste and cook over medium heat, stirring occasionally and scraping bottom of pot with wooden spoon, until tomato paste begins to darken, about 4 minutes (if bottom of pot becomes very dark and sticky, stir in 1 to 2 tablespoons water, juice from tomatoes or some of chicken broth).

After 30 minutes add green beans. Cook chicken for another 10 minutes or until done (when it offers no resistance when poked with tip of paring knife but meat still clings to bone).

While chicken cooks, simmer balsamic vinegar in 8-inch nonreactive skillet over medium-high heat until thick, syrupy, and reduced to 1/4 cup, 3 to 5 minutes (begin measuring volume when vinegar begins to cling to sides of saucepan). Set aside.

Using slotted spoon, transfer chicken to plate and tent with foil (I don't always tent it, too lazy); discard bay leaf.
