- 2 cups paper-thin slices red onions
- 2 tablespoons fresh lime juice
- 2 cups 1/2-inch-thick sticks peeled yam (red-skinned sweet potato)
- 12 to 14 ounces fresh chorizo sausages (about 3), casings removed
- 2 fresh poblano chiles, halved, seeded, cut into thin strips
- 8 7- to 8-inch-diameter flour tortillas
- 1 cup crumbled feta cheese
- Toss onions and generous sprinkle of salt in medium bowl. Mix in lime juice. Set aside to marinate, tossing occasionally.
- Meanwhile, place yam in microwave-safe bowl. Add splash of water. Cover; cook on high until tender, 3 to 4 minutes.
- Sauté chorizo in large nonstick skillet over medium-high heat until cooked through, breaking into small pieces with fork, about 5 minutes. Transfer chorizo to bowl. Spoon off all but 1 tablespoon fat from skillet. Add chiles to skillet. Cover and cook until tender, stirring occasionally, about 4 minutes. Drain yam; transfer to skillet. Add chorizo and toss 1 minute to rewarm filling.
- Cook 1 tortilla at a time directly over gas flame or in skillet until heated, 10 to 15 seconds per side.
- Arrange tortillas on work surface. Spoon filling in strip down center of each. Top with cheese, onions, and sprinkle of lime marinade. Fold in sides of tortillas.
- Often called pasillas; available at some supermarkets and at specialty foods stores and Latin markets.
