Savory Oat Groats and Kale

Heat 1 tablespoon oil in a medium saucepan over medium heat until hot but not smoking. Add onion, leek, and half the garlic. Cook, stirring, until onion is translucent, about 5 minutes. Stir in carrot and groats; cook 1 minute. Add stock, 1 cup water, and the salt. Bring to a boil. Reduce heat; simmer, covered, 25 minutes.

Heat remaining tablespoon oil in a medium skillet over medium heat until hot but not smoking. Add remaining garlic; cook until garlic begins to turn golden, about 30 seconds. Stir in kale; cook, stirring, until wilted, about 3 minutes.

Stir kale mixture into groats. Cover; cook until liquid is completely absorbed and groats are tender but still chewy, about 5 minutes. Season with pepper and red-pepper flakes. Garnish with cheese, and serve with lemon wedges.
