Simmer these little nuggets with garlic in a low-sodium chicken broth.
In a large skillet with a tight-fitting lid, heat olive oil over medium-high. Add garlic and cook until fragrant, 30 seconds. Add Broccolini and chicken broth; season with salt and red-pepper flakes. Bring to a boil over high and cover. Reduce heat and simmer until Broccolini is tender but still bright green, about 15 minutes. Transfer Broccolini to a platter. Increase heat to medium-high and simmer broth until reduced by half; pour over Broccolini.
