This delicious recipe for sauteed mustard greens should be paired with Aaron Sanchez's recipe for Duck Breasts with Ancho Chile Dulce De Leche Glaze.
Heat oil in a large skillet over medium-high heat. Add onions and jalapeno. Cook until onion is translucent, about 3 minutes. Add tomatoes and cook 2 minutes more. Add mustard greens and cook until wilted and tender, about 5 minutes.
Drizzle vegetables with lemon juice; season with salt and pepper. Serve immediately.
