Heat the oven to 200ºF.

• Remove 12 tortillas from the package; save the rest for another use.

Lay a damp kitchen towel on a sheet pan. Arrange the 12 tortillas on one end of the towel, overlapping them slightly; cover them with the other end of the towel. Heat in the oven until warmed through and just pliable, 10 to 12 minutes. Remove from the oven and let stand, still covered, until ready to use.
While the tortillas warm, prepare the taco filling.

• If using the poblano, remove the stem, ribs, and seeds; chop the poblano into ¼-inch pieces. Wash your hands after handling.
• Cut a small corner from the ground turkey packaging and drain off any excess liquid. Transfer to a plate; pat dry with a paper towel.
• Rinse the black beans.

In a large frying pan over medium-high heat, warm 1 to 2 tablespoons oil until hot but not smoking. Add as much poblano as you like, season with salt, and cook, stirring occasionally, until just tender and beginning to caramelize, 2 to 3 minutes. Stir in the tomato paste and cook until starting to darken, about 1 minute.
Add the turkey and cook, stirring to break up the meat, until lightly browned but not yet cooked through, 4 to 5 minutes. Stir in the taco seasoning, season with salt and pepper, and cook until the turkey is cooked through, 2 to 3 minutes. Stir in the black beans and cook until warmed through, 1 to 2 minutes. Season to taste with salt and pepper.
While the taco filling cooks, prepare the salsa and garnishes.

• Peel the cucumber, if desired, and trim off the ends; cut the cucumber lengthwise into ½-inch-wide wedges, then crosswise into ½-inch pieces.
• Scrape off any seeds from the roasted red peppers; chop the peppers into ½-inch pieces.
• Coarsely chop the cilantro.
• Zest and juice 1 lime.
• Cut the other lime into wedges.
• Trim the root end from the iceberg lettuce; separate the leaves.
• Crumble the queso fresco.

In a medium bowl, stir together the cucumber, roasted red peppers, cilantro, lime zest and juice, and 2 to 3 teaspoons oil. Season to taste with salt and pepper.

Set out the tortillas, lettuce leaves, taco filling, cucumber–red pepper salsa, lime wedges, queso fresco, and yogurt. Invite everyone to assemble their own tacos, using tortillas or lettuce leaves for wrappers as they choose.
