Zucchini Enchiladas

1.Preheat oven to 425 degrees F. Heat oil in a large skillet over medium-high heat. Add onion, poblano and salt. Cook, stirring frequently, until the vegetables have softened and are beginning to brown, about 6 minutes. Reduce heat to medium if vegetables start to burn. Transfer to a large bowl. Add chicken, 1/2 cup cheese and 1/2 cup enchilada sauce. Stir to combine; set aside.

2.Using a vegetable peeler or mandolin slicer, slice zucchini lengthwise into thin strips (see Tip). Discard any uneven and broken pieces. You should end up with 48 slices.

3.Spread 1/4 cup enchilada sauce on the bottom of a 9-by-13-inch baking dish. Lay three strips of zucchini on a clean work surface, overlapping the edges by 1/4 inch or so. Place 2 generous tablespoons of the chicken filling across the middle of the zucchini strips. Gently roll the zucchini strips around the filling and place seam-side down in the prepared dish. Repeat with the remaining zucchini strips and filling. (You should have 16 enchiladas.) Top the zucchini rolls with the remaining 3/4 cup enchilada sauce and 1/2 cup cheese.

4.Bake until the sauce is bubbling and the cheese is melted, 20 to 25 minutes.

5.Meanwhile, whisk sour cream and milk together in a small bowl. When the enchiladas have finished baking, top with lettuce and cilantro. Drizzle the sour cream mixture over the top.
