Step 1

For the chicken filling: Heat the oil in a large saucepan over medium-high heat. Add the tomatillos, garlic, jalapeno, onions and 1 teaspoon salt. Cook, stirring occasionally, until soft, about 15 minutes. Add the canned chiles, cumin and 3/4 cup water and bring to a boil. Season with salt and pepper. Reduce the heat, cover and simmer for 10 minutes.

Step 2

Transfer the sauce to a blender (or use an immersion blender) and puree until smooth. (When blending hot liquid, first let it cool for 5 minutes or so, then transfer it to a blender, filling only halfway. Put the lid on, leaving one corner open. Cover the lid with a kitchen towel to catch splatters, and pulse until smooth.)

Step 3

Pour the sauce back into the saucepan (if using a blender) and add the chicken, corn and beans and warm through. Taste and season with additional salt and pepper if needed.

Step 4

To serve, toast the tortillas over an open flame until just slightly charred (alternatively, wrap in a damp paper towel and microwave for 1 minute to heat through and make pliable). Add about 3 tablespoons of the chicken filling to each tortilla, top with a drizzle of crema, sprinkle with queso fresco and some sliced radishes.
