This hearty, Italian-inspired winter soup has layers of warmth from Piment d’Ville in the broth and a crown of chile-toasted croutons. We’ve made this recipe flexible on purpose; use potato or winter squash, whatever greens you like, and whatever cooking liquid you happen to have on hand. Got some fennel? Add it. Parsnips? Sure. Napa cabbage instead of kale? Why not? The whole point is to enjoy a warming bowl of stew perfumed with Piment d’Ville.
