- 2 tablespoons ghee (clarified butter) or vegetable oil
- 1 bunch scallions, coarsely chopped
- 2 dried chiles de árbol or 1/2 teaspoon crushed red pepper flakes
- 2 garlic cloves, finely chopped
- 2 teaspoons yellow mustard seeds
- 4 bunches flat-leaf spinach, stemmed, very coarsely chopped
- Kosher salt, freshly ground pepper
- Heat ghee in a large skillet over medium-high heat. Add scallions, chiles, garlic, and mustard seeds. Cook, stirring often, until garlic begins to brown and mustard seeds pop, about 1 minute. Add spinach to skillet by the handful, allowing it to wilt between additions. Cook, tossing often, until spinach is tender, 5-8 minutes. Season with salt and pepper.
